Correct part for flex fuel option

After an early failure with headers this turned out to be the header I needed for a Chevy S-10 with the flex fuel option. And I'm sure this product would work. perfect if I could remove the old manifold.

Pros
  • Replacement parts
Cons
  • Annoying

Fast Shipping and Parts Compatibility

The gasket is located between the shipping carton and the cardboard sleeve inside, protecting it from being damaged by the exhaust manifold. It would have been nice if other spacers were included but overall a great item sold by a great seller. Thanks!

Pros
  • Exhaust and Emissions
Cons
  • Quick Start Guide

Thanks Revain - Spare Parts

This header was a 100% perfect match for our 2003 GMC S-10 pickup. It was an easy install and we were very happy with the quality of the manifold. The delivery was fast and we received the package in perfect condition. All parts are there. We have a fleet of twenty cars and are tired of paying high prices for parts. Thanks again

Do not buy this title!

This after sale cast iron replica sucks! Will it fit? Yes it will. Will it crack in less than a month? Yes it will. I recommend using a head tube that sets the pace. It fits like a charm and bolts onto your standard cat with no modification. Plus its 50 state rights and give you more bandwidth. (3 to 4500 rpm) I've had the pacemaker on my truck for about 4 months now and it's perfect.

Pros
  • Automotive
Cons
  • Infinitely slow
