Ok so after buying a Magnaflow muffler last summer I have finally decided to get it put on. It is a 2.5 in, dual 2.25 out.

I have some questions. I am a complete newb when it comes to performance, I'll admit it. I don't want it super loud but when I get on it I wanna hear the GA purrr.

1. It is ok for my to leave my stock piping even if its 2.5 in, Correct? Does 2.5 piping really offer noticeable gains/noise?

2. Is there really a difference with quality of tips? Do I have to get 2.25in for tips? And how would 2.25in and 3out sound? Where should I look for decent tips?

3. New cat converter a must? Deleted resonator?


I contacted midas and tuffy and they both said around 150 installed, is this the best route?

Thanks for the help in advance. Any insight would be greatly appreciated.

1- You can leave it, it will work. Not a huge difference in 1/4 in of piping if thats all you're doing for mods.

2- Quality? Yes. Get stainless steel. Go to www.summitracing.com or something like that and pick out ones you like. Tips won't really change the sound that much, if it all. Anywhere from 2.5" to 3" tips will look fine, depending on if its a dual tip or single tip setup.

3- Depends on miles, maybe. Resonator delete is advised, gives it more growl.

Thanks a lot man.

Also, approx how long do I want each tip? What is normal?

ehhhh I dunno, I'd have to go measure my tips to find out. 10-12 inches, I suppose?

actually tip design, length and number will change the exhaust noise. why do you think that the big pickups with donkey dongs sound louder than other pickups with the same exhaust with a smaller tip

Muffler design and pipe sizing will have more effect on sound than going from a 2.5" to a 2.75" tip

well anything you do will change the tone and decibel level, but some have more effect than others...

I found on mine the high flow cat made the sound a lot more aggressive. It couldn't hurt to look into that also. I think i paid $80 for a 2.5" Magnaflow from Jegs and another $50 to have it installed.
