On the weekend i fitted a new exhaust to my 97 XR8. I fitted EL GT headers and cats and then 2-1/2 inch stainless with one muffler. On Friday i ran it up on a Dyno dynamics dyno and got 113kw. Today when i ran it i got 108kw. I've lost 5kw and my tractive line is also lower than what it was with the original exhaust.
Anyone got any ideas???
