DETAILED DESCRIPTION
With over 300 hp on tap, the 04-06 GTO is capable of blistering performance. JBAs first offering for the GTO comes in the way of high performance headers that elevate that performance. Starting with the oversized ports and smooth flowing 1-5/8 mandrel-bent tubing, these headers give an unrestricted path for spent gasses leaving the engine. They merge in to JBAs patented Firecone high flow collector for improved exhaust scavenging and reduced turbulence. The result is a gain of 30+hp and 34+ lb.ft. of torque at the rear wheels.
