Stainless Works Headers 1-7/8" With Catted Leads Factory Connect

2006-13 C6ZO6 and ZR1 Corvette Headers with 1-7/8" dia. 31" long primaries with "D" shaped port matched flange and 3" slip fit collectors. Includes 3" X-pipe, metallic substrate high flow converters, O2 extensions, Accuseal clamps, clamp/hanger assemblies, oil cooler lines, compression fittings, zip ties, cable clamps, etc. The most powerful LS7 headers available! For cars running mild head and cam packages, low boost superchargers or NOS. Will require dropping of front cradle and rerouting the oil cooler lines, but the increase in power will be worth the effort. Our 2" headers were dyno tested on a stock '06 ZO6, these headers picked up 29 hp and 41 ft/lb with no tuning! When used with a Stainless Works 3" cat back, these parts also weigh 40 lbs less than the stock manifolds and exhaust system!
