These American Racing Headers are stainless steel full-length exhaust headers made from 100% 304 stainless steel with D Port matched flanges and 1-7/8 diameter primary tubes. Featuring a custom race merge collector for excellent flow. Headers include the merge pipe high flow catalyst. Designed specifically for the 2006-2013 Z06 427 CID LS7 and these headers install from the underneath with no engine lifting. To complete the system we recommend the Corsa CP14172 or CP14164 axle back exhaust system.
This system will replace your factory exhaust manifolds, catalysts and H back-pipe. This product is sold for off road use only. Not legal for sale or use in California or any other location that has adopted these emission standards.
For easy installation of the rear O2 sensors we suggest 2 of the 36" O2 extension harnesses. The front O2 sensors do not require extensions.
