(FOR AFTERMARKET CATBACK SYSTEMS)
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", 1-7/8" or 2" (for max effort applications) 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 or optional H-Pipe, for a more classic musclecar sound. For Corsa Catbacks, check out our Direct Connect specifically for the Corsa.
