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.
For Corsa Catbacks, check out our Direct Connect specifically for the Corsa. Custom sizing of the outlet of our X-Pipe this system to make installation to your aftermarket Catback quick and easy.
