So the Toce header replaces the cat and doesn't lose mid-range without a tune? Just looking for apples to apples here...If there is no change in the fuel mapping does it really make any extra hp?
I’ve not seen a dyno of just a cat delete that didn’t basically lose a lot of midrange and maybe add a few hp at the peak. If that’s the case I personally wouldn’t bother spending the money there vs a Toce setup.
