2005, 2006, 2007, 2008, 2009 Mustang GT 4.6L
American Racing Headers (ARH) 1-3/4" Long Tube Headers w/ Catted X-Pipe
American Racing Headers has merged their 1-3/4" Long Tube Headers and their Catted X-Pipe into a single convenient package for the 2005-2009 Mustang GT that looks, sounds and performs amazingly.
ARH headers are entirely made of 304 stainless steel centered around 1-3/4" primaries that lead down into uniquely designed collectors that feature scavenging spikes for optimum flow. 3/8" flanges provide a leak-free seal to the engine.
The catted X-pipe features stainless steel construction and high flow catalytic converters that generate better airflow characteristics than stock. The X-pipe is a direct bolt-on replacement for the stock mid-pipe and catalytic converters.
