Let me just say that I think my stock exhaust set up is awesome. I do a lot of fast off road and single track. (GNCC type). I am looking to get a simple slip on, obviously in expensive as possible and something that will not hurt current powerband. I have gone up 1 on the rear (49 I believe), cleaned up jetting so she runs strong. Question 1 - What slip on's have you guys tried and what should I expect? Question 2 - Will a sl;ip on really give me added performance w/o header?? Question 3 - Any other options?? Thanks for the input!
