I bought the Leo Vince exhaust on ebay last week and finally got it installed today. All I can say is WOW!!!! My Spyder has grown testicles.:thumbup: There is such a tremendous difference in sound and appearance. I also unhooked the battery for a bit so the computer could reset, and it ran just as smoothly as before, but now it has some attitude. For anyone considering an aftermarket exhaust, I would highly recommend the Leo Vince! The db killer helps keep it from being too obnoxious and gives it a nice deep tone.:b2b:
