i'm looking for a new muffler to change the tone of the exhaust on my 99 gagt. so far the flowmaster 80 series is sounding nice. any other suggestions. and also is that a good muffler. i dont want a full cat back system. and will that 80 series give a more aggressive rumble to my car? i'm open to all suggestion, i just wanna get a good muffler to give a more aggressive tone/rumble to my baby.

Let someone drive your car and have them do a drive by. That's how i found out my car sounds very strange, not bad. But when you hear it, it sounds like I should be a way smaller car.

I have the flowmaster 80 on My Z24. It sounds pretty good I think, but I also put bigger mandrel bent pipe, and removed the cat. Another muffler You might want to look at is the Hooker aerochamber. The make one just like the 80 series. Theres a couple people on v6z24 that have them on there car. They sound really good too. Hers a clip of whitelightnings car off of v6z24. His exhaust is the best sounding v6 I've ever heard. He has other clips, but I can't find them. I actually think Hes a member on here too.

Flowmaster 80 has a very good rumble at idle and low RPm's but when you get up higher in the RPM range it gets a bit raspy, especially with headers :angel.

The first video is a SLP muffler which is no longer made for GA's you have to luck out by someone selling one. My 80 series got a lot more raspy after the headers, before it was a little but really not bad, I also cut the resonator off at the same time I got it (before I got the headers) so that added a lot to the raspyness. The 40 series is single in single out, while the 80 series is single in dual out.

THANKS FOR ALL THE HELP GUYS!!!!!!
so then on my 99 grand am gt i would need the 80 series rite? for the dual exhaust? also when you guys say raspy do you mean like pingy? so i think i'm goin with the 80 series. what kind of performance gains should i expect to get from it, all's i plan on doing to my car is the other than the exhaust is,CAI, and a pcm tune. i am running royal purple 5w-30 full synthetic. with all that done and the exhaust what kind of gains am i looking at as far as acceleration and torque and hp. the main thing i'm looking for is increase in accleration. and also the car has 76000 miles on it.

so are you sure thats the one i need? and just out of curiousity whats the difference between that one and the others

Some of those have 3" inlets, and some have bigger muffler cases. You could really use any of them You wanted as long is it was a crossflow style. Its just it would be much easier to have a 2.5" inlet than a 3" inlet.

bouji1
04-15-2009, 06:43 PM
are there any advantages of a bigger case? and what size tube is one the car 2.5 or 3? i believe its 2.5 but not sure. wold i get any more performance out of 3 inch

blondiez24gt

No, the only difference You'd have with the 3" inlet compared to the 2.5" inlet is You'd have to have an adapter going from 2.5" to 3". Its really just a pain. The bigger cased mufflers would just be bigger, and take up more space. There would be no advantages to run a bigger one on our cars.

Correct me if I'm wrong, but with a bigger pipe, there isn't as much pressure so you lose lower end power, right? Unless you have boost.

Yea if You were to run all 3" pipe from the downpipe back it would definetly lower Your low end power, on a stock engine. It probably wouldn't make a ton of difference, but I'm sure it would be noticeable. It might not actually make You lose low-end power but more likely move Your power from down low to all high. It would prolly help Your top-end alot though!:D I'm no pro on all this stuff. I just know the basics. Heck I could be completely wrong about all the stuff I just said!:( I'm sure someone will give a really good explanation! lol

biggest i would suggest is a 2.5 in dia. pipe. 3 in is too big unless you boost.

04-16-2009, 11:04 AM
ok 2.5 it is
