Need more aggressive sound

[wyldechild54]

Hello everyone. Right now i am running stock manifolds with an o/r prochamber and flowmasters. I am thinking of changing up my exhaust to get a more aggressive tone. I dont know if I want to go all out and get Lts or switch up the catback. Do you guys have any suggestions?

Just change the Flows out for the MAC SS 2.5 catback, that's what I will be doing in the spring.

catback would be the simpliest thing to do, LT are a bitch and you dont gain much untill you get into higher boost. I suggest hitting up the exhaust soundboard and picking what sound you wanna go with! IMO flowmasters and our cars dont mix!

You don't need to change the headers. Start with the catback, if you're looking into something more aggressive, maybe SLP LM, Stingers or MAC 3" which my car has.

Wow, that MAC 3" exhaust sounds fantastic!! I have stayed away from MAC for years, but would love to find a 3" system to swap for my M55's. Was leaning towards JBA or even Dynomax, but might have to look at MAC again!

Do you guys know if MAC sells a SS catback. Part of my reasoning for changing up my exhaust is so I can finally polish the back end

I had MAC 3" on my IRS and absolutely loved it! Sounded great! The MAC I have on my SRA just doesnt sound the same!

Ok I am thinking of this bad boy.

thats on the mac website too (30 dollars cheaper at V8 power though), its 2.5" is the only downside!

Unfortunately only the mac 2.5 system is SS. The 3" system is aluminzed steel but sounds amazing :beer:

 

[wyldechild54]

Im sure the 2.5 will sound beefy though right? Does that 1/2 inch make a big difference in tone?

 

[2003DSGMACH1]

I know monX has 3.0 mac catback but don't what else has as far as mid pipe and headers. But I have 2.5 mac's with a prochamber and mac long tube headers and mine don't sound any where as good as his. But as I said I don't know what else he has:shrug:.

 

[Root1022]

Im pretty sure the exhaust i had on my irs was 3" and one my SRA is 2.5" and it sounds completly different, i miss my IRS exhaust!

Looking to upgrade myself....do i need to get the 3" or can i just put 2.5" MAC mufflers in my bassani piping? part#'s for MAC muffs?? What mid pipe should i get instead of my bassani? Should i get an H-pipe? Not afraid to spend $ if i need to. Want mine to sound like the vids Also will the 3" system bolt to a 2.5" mid pipe? Any help appreciated, thanks in advance.

A 3" catback should bolt to a 2.5" midpipe, the flanges as far as I know are all the same, thats all that matters. And here's a link to MAC's muffler section. I'm sure if you did some searching you could find a cheaper set!

[greengt88]

checked the site, which ones will interchange with my current bassani's? Hate to spend all the $ on the 3" kit that will probably fit like crap, when i could just swap out mufflers and keep my nice fitting bassani piping. Will it have that sound? or is the 3" necessary? Still wondering on what mid to use also, help me out i can't watch anymore youtube clips.
