If you want to do it for real cheap...chop off the muffler and clamp in a piece of flex pipe. With the flex and adapters it'll cost you about 10 bucks. Did that on my s10 I had in High School, but no guarantee on longevity.:thumbup:
Lol here is my professional setup to be completely honest I kinda like it. The sound it makes is great but just how loud it is, is the reason I got a aero turbine. I'm just waiting on getting it installed because it isn't too bad right now.
Don't forget to drain diff oils, and let all air out of all the tires. I know that's flat tires are +225 hp and no gear oil has to be right around +50 hp. But there are no.guarantees on how much you will improve. Or like the added horsepower lol
