Ok, so I really want to get a Greddy SP2 catback because it's one of the quietest catbacks out there with a nice tone. However, they apparently don't make one for 5.5th gens... only 4th and 6th gens. I am wondering if it's possible to install a 4th gen catback on a 5.5th gen. Is there really is a huge difference between the catback design of the 4th gens and 5.5th gens? They appear to be the same to me. If there are any differences, is it something small that a competent exhaust shop could get around during the install?

 

just go warpspeed

 

warpspeed sells catbacks? thats news to me.. i'd have to hear what they sound like.. but for now im gonna try to stick with SP2 if possible.. does anybody know?

 

if you could get just the muffler than it will go on and just have an exhaust shop finish teh cat back.

 

see, the thing is that i really like the tone and noise level of the SP2.. and all that has to do with the design of the resonator as well doesn't it? i don't know if an exhaust shop would be able to replicate it
