Very good fast shipping. But luckily all was in good shape because the box it came in was torn into pieces amazing parts didn't fall out.

Great plugs to gain clearance

These plugs are the only performance plugs I use to gain clearance from the headers, besides them being Accel brand.

Great fit

Ordered these headers for my 04 Gto that I ls3 swapped and they still fit perfectly and sound a lot better than my stock headers with a cat delete. Getting it tuned next week will see how they perform then

I am very impressed with the quality of these headers, especially for the price. I have purchased $500.00 headers that don't look as good as these do. Excellent product!

Item looks good but have heard after buy that manifolds will not hold up to their black color after they are mounted and use. I am hoping that this is untrue. We will see
