11-14 Shelby GT500 MRT Extreme Non catted H pipe

The SVT second-gen Mustang Shelby GT500 is already one of the most powerful, commanding and eye-catching cars you can get in factory form. For the GT500 track enthusiast looking to improve the power of their unique pony and squeeze even more from their machine, we offer the 2011-14 Shelby GT500 Extreme Non Catted H Pipe. We engineered this system to take your ride to the next level in both sound and performance. The MRT Extreme line offers our most aggressive sound: an "always on" rumble at idle releases into a frightening roar that screams "take no prisoners." We achieve added performance by maximizing exhaust flow and reducing back pressure: our h pipe design (over x pipe) offers a freer and more direct exhaust path, meaning MORE power and efficiency. The H pipe also deepens the exhaust note, giving a deeper, smoother and more refined tone than the X pipe common in many Mustang high-performance after market exhaust systems. Turn heads and pay tribute to the racing heritage of the '67 Shelby GT500 with a signature muscle roar that is reminiscent of the 60s and 70s exhaust sound. In addition, we use 2.5" mandrel bent tube that is the highest quality, corrosion resistant T304 Stainless Steel, so you know this high performance mod is built to last. We handcraft each system in the USA and design our parts to be bolt on for the DIY back yard mechanic.

Our off road systems are not for the everyday driver, however: as a non-catted exhaust system, our Extreme H Pipe without catalysts offers the highest possible power, torque, and fuel economy gains, helping put you out front in a rally meet or a battle among friends. Note that because the system removes the catalytic converter, this exhaust is not legal for use on public roads. Made specifically for racing and other private uses, it's one of the easiest ways to get you roaring in front of the pack. Extreme is the loudest MRT exhaust line - even louder than Sport Touring and Street Race exhaust systems.

A Fast Way to Upgrade

Swapping your Mustang GT500 H pipe is one of the easiest ways to Hear the Difference, Feel the Performance and Get Noticed - just one mod will improve your fuel economy, horsepower, and exhaust flow. The initial installation takes just an hour using standard hand tools, though tuning may be necessary to get the maximum impact. Made of T304 stainless steel with mandrel bends, the 2.5-inch tubing is designed to match the loud, proud DNA that sits inside one of the most famous American cars. Note that since this product is non-catted and can only be used for racing, shows, closed circuit track days and other off-road applications.

Looking for even more gains? You can install the H pipe with an MRT 2011-2014 Ford Shelby GT500 Sport Touring Axle Back. The two products combine to produce the effect of an advanced cat back exhaust, giving you a big boost in horsepower and efficiency. All our systems are designed, engineered and handcrafted in the U.S. with a limited lifetime warranty.

This product is designed for off-road, race use only.
