List what you got. parts, company, price, installation, describe the sound, post a picture of the muffler and tips.

I know I am going for Borla right now, but just wanted to see some other options before I do it.

thnx.

[Dr_Kyle]

I have the single magnaflow setup with 3" tips. I got all the parts and install for around $200. The sound is deep and throaty, but very smooth. It's loudest around 2k rpm and gets quieter as the rpm's go up. You can see pics on my car domain webpage (link is in my signature).

edit: The model # for my muffler is 12266

[GreenGT3]

I have a flowmaster 80 series muffler with some oval tips. I left the stock resonator on because I didn't want it to loud. The model # of the muffler is 42583, it is tipically used on camaro's. The sound is nice and low, but when i get into the high rpm's it is a bit loud inside the car. overall I like the sound, looks, and the 2mpg increase. Total out the door cost was $360, and my car was the first the installer has ever done this to in his shop. So I thought that it was a fair price. He spent a lot of time on it. here are some pics.

I have a ?. Is there any real difference in running a single muffler with 2 outlets that running 2 mufflers?

BTW, I like your car Green.

[ash]

These are my dual magnaflow 14815's. I paid about 320 total for the mufflers and shipping and 200 for installation. Installation took around 3-4 hours. They sound great, no high end at all, just a nice deep sound. Not throaty, but rumbly. You can really feel it when you can't hear it. There's a link to the sound clip in my subscript. I absolutely love the sound. They make my car sound like it should. They're not too loud and not too soft. As starfire put it "If they were any louder I wouldn't like them and if they were any softer I wouldn't know why I bought them." So don't worry about the volume like I did... absolutely perfect. I started up my car right after I got them and I knew I made the right choice.

They're 2.25 inch inlets (same as the pipe) and they needed a custom y-pipe to be made by the shop. I ordered from www.exhaustproslinc.com (husker high performance) and it took six days to get to my house. PM me with any questions or if you want any more pics. I have some installation pics and so does Cujo.

Two mufflers will be louder and deeper sounding.

[Drew99GT]

I went with 2.25 inch piping, no resonator, and a single dynomax super turbo muffler, with a 2.5 inch tip exiting out the driver's side. That's right, a GT with only one exhaust tip. I think it looks great, not flashy at all. I deleted the resonator because I had a custom exhaust before this one, and the dynomax super turboes are quiet. It's just a tad louder than stock, just a nice mellow performance exhaust note, very subtle but still noticeable. Inside, it's whisper quiet. Paid $180 for everything. I'll try and get pictures so you can see what a GT with only a left side exit exhaust looks like. It does leave a gaping hole in the right side where the right tip use to exit, but I don't mind it.

Got the dual Magnaflows...resonator is still on, replaced pipe just before it goes over the back, custom Y. I paid 314 for the mufflers and shipping from husker and paid 150 for the install. My install needs to be fixed a little bit as the weight is starting to make one of the mufflers aim down a little bit. I'll probably get it fixed next spring. Sound is perfect...in some of the Vicious Performance vids...any of the deep deep sounding exhaust is my car (silver car). They definitely sound much better after 4 months of having them on. They definitely have a deep & throaty sound...but it's a tuned performance sound, not "hole in muffler" type of sound. Definitely my favorite exhaust having heard all of them. I'm not saying any of the others are bad...don't get me wrong.

Just like Ash, the first time I started the car, I got a grin from one ear to the next, because I knew I made the right choice.

Check the the link in my signature to see a (pretty much) step by step installation...I'm one of the few that has the steps. It's in the exhaust album.

Thanks WhiPontiac :wave: I like having one muffler for less weight. But it really doesn't make much of a difference like the other guys have said. I ended up with a single because once the mechanic and I got the car on the lift and looked at the room, we couldn't understand how two mufflers could fit without really robbing the straight thru flow of exhaust. But even with the one I am really happy. It has been a few months and about 5,000 miles since installation and I love it better than the first startup.

So your single sounds as good as a dual setup?

What you think sounds good is just up to you.. I have been debating this exhaust issue for MONTHS! I was originally gonna go with SLP, then Borla, then a Flowmaster 80, then back to SLP and now I have pretty much decided on Magnaflow... the tips look the best, and I'm hoping they sound the best... The single muffler setups sound really ricey to me... Let the flames begin, but they sound too much like all the Civics putting around town, and I do not want that for my car. The Borla has a refined sound, from the clips I have heard, but it is just TOO quiet... and a dual setup seems to be the way to go, it just mellows the sound... I have looked for dual mag sound clips, but every link I have clicked on always ends up dead... Oh well...

I am not to sure since I haven't heard a GA dual. But i have heard my brothers cutlass with a 3.4 DOHC engine and his sounds a bit better than mine, but dont forget he has more intake and exhaust valves that the 3.4 in the GA's.

Static, why do you say that a single sounds ricey? It isn't high pictched at all. At least that is what I feel.

I REALLY like the way your exhaust looks. Are those tips what came with the magnaflow? Those rock!
Definitely making me think twice about getting the SLP :p
I'm making up a list of stuff I need to do a setup like that, and I can't even find that part # on magnaflow's site? Maybe I'm jus blind...

14215 instead of 14815 maybe?

Should direct link you to the 14815's on husker. The muffler is complete with the tips. Mine are 3" cause the 3.5" look huge, but it might be more your style :) Street series, stainless steel 5x8" if you need to navigate by force. You need a custom y-pipe designed for dual mags. It'll run you about 150-250 bucks. Mine was 200-$220 w/tax. They sound much better than SLP in my opinion because I didn't want a harsh sound to them, but in my opinion, the mags are a little quiet. Everyone says they're the loudest, but I have undercoating so I don't think they're loud at all. They sound WONDERFUL when the engines cold and become quieter as it warms up, so I'm gonna toss a CAI on there and I'll be rockin. I think they're the best choice out there. I wouldn't think twice about getting them, they were so worth it. And if you guys want a sound clip, just send me a pm with your aim screenname and I'll send it to you... I don't think my link on dropthepedal.net is working right now.

Well it's like what I was talking about... It all just comes down to the person... I don't care much for the hollow sound it has, it's rather hollow... I just expected it would sound more like a V8, considering 95% of the people on the old forums compared to one, saying "It sounded exactly like this Z28 idling next to me..." I'm not bashing, just sharing my opinion...

[ash]

Here's an angle shot...

[ash]

Here's a sideview of my car.

[Travis99Gt]

That looks totally sweet... Definitely my choice for exhaust, thanks! :)
I was going to do SLP, but nah, custom sounds neater anyways... All together i think it'll be cheaper than SLP and DEFINITELY cheaper than Borla :p

SLP will probably be about 50-75 bucks cheaper. But it will be a good 200+ Cheaper than Borla :thumbs: The 50 bucks is more than worth it to get a custom setup and a sweeter sound. Get the Mags online for cheap or go to magnaflow.com type in your zip code (locate a mag dealer) and see what sort of deal the shop'll give ya.
-Mike

[StarFire]

Magnaflows are definitely cheaper on line...at least from where that I was able to find. I would go that route.

When you get the magnaflows...give them a GOOD 3 months...they change SOOOOOO much over the three months. I have three vids (Dropthepedal) and two of them were taken within a month of me having them. One vid is the GT Sounds one...and the other is Dan & Pucci in the tunnel. If you compare what mine sounds like now...it's nothing to what it was. It is much deeper and louder now. Even GrandAmRamAir has said that he didn't like them at first because they weren't loud...now that they have broken in (where I say at least 3 months) he really likes them and can't believe how good they sound. The third video I'm on up there is the Vicious Performance Cruzin 2. I drive past the camera...and after the camera you can hear me taking off...much more agressive sound to the car in that one. :)

I say (depending on the shop) the dual magnaflows or SLP will cost just about the same (within a couple bucks). I was going to go with SLP...but I love having a more musclecar sound to my GAGT...especially when starting off.

Note that outside the car, Magnaflows get SOFTER the faster you go. So if you are expecting the sound to get a lot louder...forget it. The magnaflows are designed to get softer and allow the engine to be heard (which is where a CAI comes in perfectly).

Hopefully I can get some good vids of my car here soon and have them up on Dropthepedal.net for you all.

Ash...I think you will be the sponsor for Magnaflow on this board. lol:boogie:

I'm sure I can get the hookup on the install, but we'll see. Don't have the $$$ to shell out right now unless I wanted to put it all on my credit card which I'm thinking about, but not real sure I want to do :)
Soon as I get it set up I will definitely get some pics up :)

Star or Ash, do you think those mags would go for the 2.4L also? Just wondering in case I do decide to upgrade my exhaust. Any other advice or help is appreciated. Thanks!:D

[StarFire]

Yeah Slim25 has them on a 2.4L I believe. There are a couple of people on here that have magnaflows on the smaller engine...I know everyone says this, but I would search for, "magnaflow" and in one of the links should be the thread of people. I just can't remember which thread it is...and I don't have time to find it for ya as I am leaving for work. :rolleyes:

[Slim]

Nope... :) I've got a GT coupe with the single Mag setup. I love it!! I went a little crazy and got dual 3.5" tips for mind from JC Whitney Click for Pic (http://www.jcwhitney.com/item.jhtml?ITEMID=56075&BQ=jcw2) They looked huge off the car, but when I put them on, I was really happy. Like everyone else has said, the sound gets A LOT better after about 3-4 months. Mine has a really loud snarl to it when I punch it too. :D It's good at highway speed too. As long as I'm going above 110km/h, there's no drone at all.

Sorry Slim, didn't mean to dis ya 3400SFI. :)

[Magnum]

I have the dual Magnaflows on my '01 GT (P/N 14815, I think) w/the 3.5" tips. I got them through a local performance shop (PartSource) 'cause the manager is friend, and 'cause I have a business account there. Got them at his cost, $300 (Cdn).

I had them installed at another local shop, River City Performance, cost $400 total for mandrel bent install, 2.25" stainless piping from the resonator back. The installer made a unique-looking y-pipe that was more like a header collector.

When I first started it up, (after the 4+ hour install) it was the installer who had the grin plastered from ear-to-ear. I just blew my load in my pants. It was soooo deep and muscular-sounding. Loud, yes, but more rumbly. In my opinion, the PERFECT sound.

I've heard the Borla and a dynomax in person. the dynomax was just too quiet for me, (but still sounds really good, Anders! :) )and the borla a little bit raspy for my taste (but again, still really nice, Video :) )
They are loudest at or below 2000 RPM, and get quieter, but more AGGRESSIVE sounding at higher RPMs (3500+)
Also, gas mileage is better at higher speeds - I took a trip from Gimli to Roseau and back, did about 150Km/h most of the way, and mileage was BETTER than normal highway driving at 100Km/h. No pics for now, unfortunately.

[Cujo]

That's a pretty darn good description of how they sound Magnum. If you got p/n #14815 then you got 3" tips, same as me bro :D.

Do you think you could post some pics of your y-pipe if you have any ? Sounds like they did a really good job and I am interested to see how it looks like.

Thanks,
Cujo..

[StarFire]

Cujo, do you have the Cold Air Calibrated MAF? If so, how do you like that...I was thinking of picking it up. Notice any differences with it?

I'll post pics ASAP, I haven't had the car since Sept. 4. Some fuKKer ran a stop sign in front of me on the highway and I T-boned him. Did $11,000 front-end damage. Not a writeoff (unfortunately). I should get it back around the 4th of October.

Dammit, now I'm not even sure if it was the 3" or the 3.5" tips.... Whatever, same end result ----> :thumbs:

-=StarFire=-

Yes, I have a GMS Maf. I'm not sure if its calibrated for cold air or not. I bought it used awhile ago. It worked great for awhile but then started to cause a misfire which made the tranny act up. I put the stock MAF back on and then no more tranny problems. It took a good 8 months for this to happen though. While it worked, it probably gave a 3-5 hp gain. I don't know for sure but to compare I ran 2 tenths second faster in the 1/4 mile with it. I could chirp and squeel my tires very easily with it on.

I'm gonna try to install it again today and see what happens. On sunday I'll meet up with my buddy who has a G-Tech Pro. Its one of the newer ones that reads out hp. I don't really trust them, but its better than dishing out the dough for a dyno run.

The GMS maf also made the exhaust and cold air intake sound much deeper and the car growled very aggressive. I'll let you know what happens when I put it back on.

Cujo..

Sorry to hear about your ride man.. That really sucks :( . I sure hope they fix your car to the way it was before the accident.. Well, whenever you get some pics make sure to post em. I think you're the only one who has mandrel bent dual Magnaflow's. The rest of us have piping that's crush bent. Did you get a chance to take your car to the track at all before this happened ?

I was gonna be at the track on the 7th, but the accident killed those plans. Looks like I won't make it till next year. Why doesn't anyone else have mandrel-bent pipe? Also, to be fair, the stock piping wasn't very restrictive except for a large crush right over the rear suspension.

[Cujo]

Well I reinstalled the GMS Maf sensor with success ! One difference I noticed right away is the idle rpm doesn't jump around from 600 to 700 anymore. It stays constant at 650 rpm. When I punch it, I can very easily squell the tires now and for quite a distance too :D The car has much more mid to upper power now and accelerates much faster. The tranny doesn't buck at all anymore or hesitate when I floor it.

On sunday it was raining so I didn't get a chance to use my buddies G-Tech. I'm just happy this GMS MAF is working again ! Hopefully it will continue to work and I won't have the problems I had before with it.

[GreenGT3]

The GMS maf is considerably larger than the stock Mass Air Flow sensor. It allows for more airflow and supposedly has more aggressive readings than stock. Its not new, its been around for awhile.

You can find more info about it on www.gaupgrades.com . Just scroll down to performance section and click on Granatelli MAF. You can buy them new at Muscle Motorsports for about $300 US or so. I got mine used for $100 quite awhile ago so it was a good deal.

More info can be found directly on their website HERE (http://www.granatellimotorsports.com) . I find it works really well with my setup, but it don't work at all for the sc guys. The calibrations aren't right and their cars won't even idle properly with it on..
