C6 header gains
C6 header gains What kind of gains (rwhp) can be expected from LT headers? I've heard as much as 40, sounds a little too good to be true. I'm dynoing the car on Friday, just trying to get some early predictions. BTW the headers are Kooks 1 7/8 with 3 inch merge collectors & a 3 inch x-pipe with metal substrait cats. TIA

I never did a before dyno with my Kooks 1 3/4" headers. I did run the 1/8 mile, a week apart in similar weather. The DA was about 2500-3000' and my best pre-header (cat-back, tune, cai) was an 8.7@86.4 (2.1 60-ft) while after the headers, a best of 8.41@89.39 (2.1 60-ft). My only dyno with the above mods and headers was 378rwhp/358rwtq SAE.
Aric,
Will be interesting to see what it will do with the headers. Maybe 117 mph? Your car flies already for stock. I hope mine will do even almost as well.
If you are installing headers with cats be sure to clean everything out of the ID of the headers and pipes upstread of the cats. Although I have not seen any Kooks pieces, almost every other brand I have seen had metal shavings, weld slag, grease and other pieces of crud that will at least block some of the cats flow capability. Keep in touch!
