Car is 2010 supercharged Roush 4.6L 3V (forged internals), dyno'd 625rwhp, so about 700 at the crank. I want equal-length long-tube headers. My main goal is to get a nice smoooooth exhaust note and I've always had good luck when using 'tuned' headers.
Also looking for good fitment and relative ease of installation. Plus I would like the headers to take as much heat as possible out of the engine compartment, I kinda think ceramic coated might be best for this???
Size-wise, I am thinking 1.75" with 3" collector. I know that may seem small, but I am not interested in every last HP at max RPM. I want mid-range punch and smooth drivability.
I intend to re-use my existing 2.5" stainless steel system (Pypes hi-flow cats and x-pipe and Corsa muffs). I will TIG the system as needed for proper fitment to the headers, and likely add a couple of SS braided flex couplers just after the cats.
Many thanks for any help! Dave F. in RI
