this would explain why nitrous is far from interesting to you.. if i were into autocross nitrous would NOT be my weapon of choice... i agree with your statement about everyone in the world thinking nitrous makes a nine second car.. but i pay little attention to that stuff, i use what works.. my answer to his question was SEMI-OT, but it was a REAL answer.. exhaust is cool, as in intakes.. hell a header is a pretty cool mod also.. but its pretty sad when you add ALL that stuff and MAYBE shed a couple tenths off of your time (if that) so my input was save for something that will matter.. i would invest in good suspension before an intake or exhaust.. at least that improves the car dramaticly, over just making it louder...
