I decided to try something different this time around when testing a product. Instead of checking to see if it got hurt evertime I went over a bump, I decided to do a couple runs, and then check out the headers after that. Here is my opinion. 4.2 The installation was a pain in the butt.
And the headers are so close to the front pumpkin, that when full flex of the left tire up, and the right tire down, the pumpkin bends the header pipe inward.
Bottem line: Spend 200 more, get a Borla.
