    As long as all the emissions sensors are left alone, it shouldn't.

    no it won't. the only thing that may get messed up is your hearing, good standing with your neighbors, and the cops..straight's with no muffler(s) crackle, pop, and sound like S**T IMO

    Long tube headers and off road y with no cats makes it loud! Choose your muffler carefully and it will sound really good too. I want to try a spintech 9000 with my set up.

    If you're going Flowmaster, the 10 series is the one you want if you're trying to get loud. You might want to look into Cherry Bomb Extreme if you're going the chambered route.

    I hear the spintech 9000 is really loud and sounds great. The cherry bomb is definitely loud, prob doesnt sound as good as spintech though.

    If you like loud glasspacks and popping, go ahead and run straights because it sounds like they are right up your alley.

    You get AID's when you run straights too
