    Ready to Ride. Want maximum performance on your competition Mustang? Check out the MAC Pro Chamber Mid-Pipe for Off-Road Cat Delete Pipes. This chamber does more than a traditional H- or X-pipe. It actively merges the flows coming out of both sides of your Mustang's V8, allowing the complimentary power cycles to support each other in speeding the flow of exhaust gases out of your engine. The result is a great tone and wildly improved power, torque, and throttle response. Keep in mind it's not street-legal, and isn't for use on any on-road emissions controlled vehicle.

    Power Increase. This chamber, when used in conjunction with the MAC 45012 Off-Road downtubes, produces great power increases. It removes the separation between cylinder banks, and allows more gas to flow faster. That's the essence of what a power-boosting exhaust system should do.

    All-Stainless Construction. This is a quality piece. MAC forms it out of 100% stainless steel, so it will never rust through. All curves in the pipes are mandrel-bent for maximum internal smoothness. Just like your Mustang, it's made in the USA.

    Easy Installation. This chamber installs with stock OEM hardware. It's a bolt-on installation.

    Application. This MAC Pro Chamber Mid-Pipe fits your 2011 through 2014 Ford Mustang GT 5.0L V8 when equipped with MAC Off-Road Cat Delete Pipes part# 45012. This part is not legal for road use on any emissions-controlled vehicle.
