The NEW! GTSpec 02-09 WRX STi Equal Length Header is crafted from 14 Gauge SUS-304 Stainless Steel, GTSpec's headers are tigwelded inside and out to ensure a perfect flow and fit.

Combining an industry leading mandrel-bent 45mm stainless steel piping, .5-inch thick CNC machined SUS304 wax-cut flanges and SUS304 02 bungs means a performance part with the quality and craftsmanship you deserve. GTSpec products are an upgrade exclusively for those seeking the ultimate in engine performance.
