So I been looking at full exhausts and slip ons. I came to realize that full exhausts are super expensive. Cant see myself paying $2,000 to gain 10 hp. IF that. So Im def. going with a slip on. Now I been thinking about other stuff to gain some hp. So maybe some heat resistant wrap and cutting out the cat and throwing in a straight pipe. What do you guys think abut that combo?? I know a full exhaust with header would be prime but not for that kind of money. You think I would see any gains by heat wrapping it and cutting out the cat???
