As another reviewer noted: This does NOT fit the Chevy Trailblazer. I didn't listen and now I'm giving it back, a big pain in the $$. I've visited several other websites (Summit, Rock, Flowmaster, etc.) to check compatibility. Everyone says it fits my Trailblazer, but as the reviewer said, the flange doesn't match the manifold. I will say the curves and length, the quality of the material is all good. But none of this matters if you can't complete it!
