2005-2010 Mustang GT 4.6L Stainless Works 1 5/8" Headers w/ Cats and X-pipe Included

This version of Stainless Works' combo kit uses their 1-5/8" headers and a high performance catted x-pipe to boost overall performance on 2005 to 2010 GT Mustangs.

SW's headers are crafted with top-quality 304 stainless steel that's TIG welded for additional strength. Each 1-5/8" primary attaches to to 3/8" thick flange that's precisely matched to the OEM connections on the 4.6L V8. The 3" smooth flow collector enhances exhaust flow.

The catted x-pipe features a crossover design with specially designed high flow catalytic converters that offer substantially better performance than the stock designs.

Each kit includes installation hardware and 24" oxygen extensions. The x-pipe is a direct bolt-one replacement for the factory mid-pipe and catalytic converters.
