ARH long tube headers offer a no hassle installation. There is no need to dent primary tubes to clear the steering shaft or starter. The headers clear everything perfectly with room to spare. ARH machines 3/8" thick flanges that resist warping. Flanges are TIG welded to the primary tubes then ported to create the smoothest flowing exhaust possible. The 100% leak free one-piece long tube design keeps exhaust parts to a minimum and creates a straight forward installation. ARH long tube headers extend towards the outside of the car so removal of the transmission does not require removing of the headers.
A 2-1/2" h-pipe connects to the long tube headers with a slip fit design and it bolts directly to your factory cat-back. Ultra high-flow 200 cell metallic substrate catalytic converters provide the ultimate exhaust flow while still passing emissions laws. The 2-1/2" h-pipe will bump up the decibels of your Mustang while providing a deeper and less raspy tone.
Installing long tube headers is quite the task and not something you want to do twice. No one wants to remove headers a second time to deal with loose bolts or an exhaust leak. The high quality ARH headers and h-pipe provide perfect fitment and sealing so your install is done right the first time. Along with great fitment comes fantastic power gains and an aggressive exhaust tone. Made in the USA!
