All Budget Headers are NOT Created Equal!
Hooker's Competition Series Headers come in your choice of finishes and are engineered to perform at a reasonable price! To let your engine really breathe, Hooker utilized 16 gauge (.049'' thick) steel tubing attached to long transition style collectors. Giving you a serious increase in flow over other brand headers without a loss in the backpressure most engines need to perform! After years of testing, Hooker has discovered that a machined 5/16'' header flange offers enough flex to hold the gasket tight to each exhaust port plus enough rigidity to keep everything properly tied together.

Features

Mandrel-bent tuned-length tubing for smooth exhaust flow and power
Sturdy 16 gauge steel tubing
Perfect seal 5/16'' machined header flanges
Long transition collector for improved power over standard headers
