2005 2006 2007 Saleen Mustang Body Kit at HaneyMotorsport that i need a saleen center exhaust kit or need to modify the factory exhaust tips...now im a noob when it comes to anything like this...i wanted to put slp loudmouth on the 05 v6 but i think this may change it...and to be honest i barley know anything about cars..i just know my cars and not how they work...so if anyone can give me any advice on what to do but still keeping a tight bugget by making the car very loud and still being able to fit the saleen body it i would greatly appreciate it..and if you could give me an estimate on how much this should cost to get installed or moddified that would rock as well

thanks
