The latest generation of Mustangs brought performance and handling to a whole new level, but power and torque as still waiting to be unleashed from an anemic factory exhaust. With header systems in 1-3/4" or 1-7/8", and a 3" exhaust, our Bottleneck Eliminator Kit unlocks that power with performance gains up to 30 RWHP and does away with the 2-1/4" restriction at the Catback connection point. Designed to work with aftermarket Catbacks exclusively, a simple mark and cut (no welding required) mates the ARH Bottleneck Eliminator to your Catback. Comes with a 3" X-Pipe standard for a more classic muscle car sound. For Corsa Catbacks, check out ARH's Direct Connect specifically for the Corsa here.
The video below was shot with an X-Pipe equipped Full System with ARH Pure Thunder mufflers. The sound may vary depending on mufflers used. Consider upgrading to the Full System if you like the sound.
ALL American Racing Headers Exhaust Systems are for OFF-ROAD use only.
- Choice of 1-3/4" or 1-7/8" headers
