ok the header has been installed on a completely stock car, and 300 miles has been put on it over the last 24 hours just to make sure everything was working. there won't be a review of it until tomorrow afternoon when the dyno #'s have been posted. but just fyi the stock manifold collector where the pipe connects to the downpipe is only about 1.5" wide! yes i'll post a picture of it tomorrow. the manifold is pushing out the entire engines exhaust through what looks like 1.5" wide by 1" high (roughly) when i seen that i just started laughing and everyone else around was dumbfounded as well that they would do something like that from the factory. very small compared to the 3" collector on the tog system updates tomorrow on #'s

Can't wait for the dyno!

Sweet let us know soon as it rolls off!

I measured mine to be about 2" but I was upside down under the car holding up a tape measure. I will reafirm that it was one of the worst stock manifolds I have ever seen.
