Z06 stock headers and pipes my widebody
X pipe (3"). My old manifolds and pipes were 2 1/2 inches.
We put them on Friday and all went fairly smooth. Found a neat way of cutting back the upper 02 sensor harness out of the main taped form and pulling it back 9-10". Then just simply retaped the original form and sensor wire with black tape again. Looks like factory again and we didn't have to use 02 extensions. All fit well except we didn't have the proper exhaust pipe reducers going into my corsa exhausts so we made some temporary ones and put them on. I will be changing them out next week.
The car pulls much harder. I estimate I got another 20RWHP. We will be retuning them very soon. I had 378 RWHP with a Halltech stinger, ported and polished TB and intake, corsa exhausts and a tune. Should be aproaching 400 RWHP or close to it.
