American Racing Headers (ARH) 1-3/4" Long Tube Headers w/ Off-road X-Pipe
This American Racing Headers combo kit comes with a set of their 1-3/4" Long Tube Headers and their matching Off-road X-Pipe. This ARH package is designed to fit and improve performance on the 2005-2009 GT Mustang.
ARH headers are made with high-grade 304 stainless steel. The 1-3/4" primaries connect to a stout 3/8" flange that perfectly fits the 4.6L V8 with no modifications. The 2-1/2" venturi-style collectors feature scavenging spikes that further optimize outflow.
The off-road X-pipe is entirely stainless steel and deletes the catalytic converters which eliminates back pressure for increased horsepower. The kit comes with all necessary installation hardware and instructions. The X-pipe is a direct bolt-on replacement for the factory mid-pipe and catalytic converters.
