Product Details

The Stainless Works GTOHCAT is a complete long tube header kit engineered for the 2004 Pontiac GTO. Built from corrosion-resistant 304 stainless steel and fully TIG welded with back purging for exceptional strength and durability, this kit delivers meaningful exhaust flow improvements over factory manifolds.

Construction & Design:

  • 1-3/4" primary tubes — CNC mandrel bent for smooth, unrestricted exhaust flow
  • 3/8" thick CNC laser-cut flanges — precision machined for a leak-free seal
  • 3" slip-fit collectors — optimized for maximum scavenging efficiency
  • Fully TIG welded and back purged — ensures clean, strong welds throughout

Included Components:

  • Left and right long tube headers
  • High-flow catalytic converter lead pipes (3" diameter)
  • 3" lead pipes with 2-bolt factory flange connection — bolts directly to the stock exhaust system

Quality & Warranty:

  • Manufactured from 304 stainless steel for maximum corrosion resistance and long service life
  • Engineered for optimal ground clearance and precise fit
  • Proudly made in the USA at Stainless Works' facility in Streetsboro, Ohio
  • Backed by a lifetime warranty on materials and craftsmanship
