2005-2010 Mustang GT 4.6L Stainless Works 1 5/8" Headers w/ Off-Road X-pipe

This version of Stainless Works header combo kit replaces the more standard lead pipes with a x-pipe crossover design. The kit comes standard with SW's 1-5/8" headers and an off-road x-pipe, both built for 2005 to 2010 GT Mustangs.

SW's headers employ 1-5/8" primaries and 3/8" thick steel flanges that perfectly connect to the Mustang's 3V V8. The 3" collection tube uses a smooth flow design to enhance exhaust scavenging. The entire header system is constructed from TIG welded, 304 stainless steel.

The off-road x-pipe features a crossover design that provides better outflow than standard lead pipes or the factory mid-pipes. The deletion of catalytic converters makes airflow eve more efficient.

Each kit comes with installation hardware. The x-pipe is a direct replacement for the factory mid-pipe and catalytic converters.

Kit components: Includes Stainless Works 1-5/8" headers and an off-road x-pipe.
