2015 392 Shaker Challenger
Happy with my order and purchase. I was on the fence between Stainless works and another brand, but these headers are high quality. In relation to power, it is a very noticeable gain and I have not tuned my car yet (it feels like I am on Track mode at the default setting). The sound is great, nice rumble, not loud at all until I go WOT lol. On another note I did notice that my gas mileage improved by up to 3mpg. So I am very pleased with my Stainless works long tube and i got high flow mid pipes
Chevy II long tube headers.
63 Chevy II, Chassisworks clip, LS1, T56 tranny. I did not use the supplied motor mount adapter plates. The quality seemed good. I did spend a little time to deburr the holes and used a file to break the sharp edges. On my car the fit was good with the exception of the driver side O2 sensor. It would not work in the spot designated for it as it interfered with my stock floor pan. I ended up putting a plug in the bung and welding a new bung just downstream of the header. Satisfied overall.
