hey guys, recently bought a 02 procharged gt. The gt came with kooks L/T headers, pypes x-pipe and Magnaflow cat-back. This being my first supercharged mustang, i'm not quite sure of the exhaust note. It has a really ugly rasp at low rpms under light to moderate acceleration but a very nice tone at WOT and high rpms. My question is, is the rasp normal? Also I'm a die hard when it comes to Flowmasters (nothing sounds better to me), are there any guys or gals out there with supercharged gt's with Flows? A sound clip would be awsome! Thanks yall.
