Description of Dougs Headers D331 Metallic Chevrolet

Thick flanges (3/8 inch to 5/8 inch) with no warping. CNC mandrel bent tubes for an accurate fit and a better flow. Precision formed long transition collectors that reduces backpressure. Heavy gauge tubing (16 and 14G) for longer life. Header tubes are pre-polished for a better appearance.

Boosted My Car's Performance!

As a result of my tests, I determined that this exhaust system increased my car's horsepower and torque, giving it a more aggressive sound .The metallic finish also looks great on my Chevy. The installation process was a bit complicated and took longer than anticipated..

Pros
  • Improved performance, stylish finish.
Cons
  • Complicated installation.

Beautiful product and very well built.

They didn't fit our large Gen V unit, had to send them back. We installed them on a 1970 Elcamino SS 454 with a rebuild V 502 generation engine. On the passenger side they did not clean the air conditioning housing and on the driver side they did not clean the oil filter radius block. It's a shame because it's a very nice design.

Pros
  • Precision molded long adapter manifolds to reduce back pressure
Cons
  • I vaguely remember
