i dont agree with the "sounds like a v8" i mean prove me wrong i havent heard everysetup but compare my friends turboback wrx with an uppipe and headers.. it sounds nothing like my other friends 2003 mustang with full exhaust... sure the WRX sounds damn burly and big but the v8 vs the unequal header wrx have two different sounds when they are truly flooring it. the wrx has the loud n burly rumble, but the v8 has a loud many piston roar. just my opinion, but other people have seen different things.. no one can say theyve really seen it all.. theres too many combos that can be done to change the sound. and ya muffler affects a lot of the sound. for example the borla hush sounds very different than the HKS carbon titanium..
keep it in the dirt.
