    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.

      MAC Pro Chamber

      Fantastic upgrade when paired with MAC Cat-Delete pipes on a stock exhaust. With the factory manifolds and mufflers, your car will retain a similar exhaust note just deeper and more aggressive. These are deigned to pair with the MAC Cat-Deletes but doing so ended up with an exhaust leak on both pipes, so I had to get a shop to weld the two pieces together. Your car will be slightly louder because of the Catalytic Converter removal, but it's not louder to the point of annoying and honestly you probably would still think nothing was done to the car while you're cruising around. In the end, this product offers a nice mellow rumble to regular driving, but give your car a throttle and it'll a sing a nice song for you.

      Makes car sound deeper

      Very good product. I actually used this on a v6. I had an exhaust shop make sone adjustments to make it fit.
