i would leave the cats out if local regulations permit, other wise put in larger Hiflow cats. Ans as suggested above, do the headers at the same time as the rest of the system! It is a big job and makes the rest seam simple. You will also save Lots of money, and it will allow the exhaust shop to build a proper system in one go. I got 148rwkw with headers, hi flow cats, twin 2.25 and BFI. ~20kw gain for about $1800
