Awesome company

Ordered the Speed Engineering axle back exhaust for my Corvette, it shipped same day with free shipping, and was priced less than buying directly from the manufacturer. New customer for life 👍

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!

big T review

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
