Product Description

The MRT "MaxFlow" non-catted H-Pipe available for the 2011-2013 Shelby GT500 Mustang, the only mid-pipe exhaust system on the market with that muscular sound all performance enthusiasts love. The MRT H-Pipe deepens your exhaust note and improves the flow of exhaust gases by maximizing mid-pipe system volume. The MRT H-Pipe increases horsepower, torque and fuel economy while still sounding muscle car tough.

The MRT MaxFlow H-Pipe is made of the highest grade 304 stainless steel, making it light-weight and durable for years to come. This system includes bell-mouth flanges for a leak free seal. All MRT H-Pipe exhaust systems feature CNC mandrel-bent tubing to guarantee precise, factory-caliber fit. Installation of the MRT H-Pipe is simple and drill-free. The MRT MaxFlow H-Pipe Exhaust clamps-on directly in place of the factory mid-pipe exhaust.

Catalytic converters are NOT included in this offroad version. Please note that all MRT H-Pipes are custom systems intended for performance use. We make no claim of compliance with local, state or federal emissions standards. Please take the steps to learn about regulations in your area and use on main roads at your own risk.

All MRT exhaust systems are engineered and produced by MRT Performance.

  1. 2011-2014 Shelby GT500 MRT Maxflow H-Pipe Exhaust, without Cats 5 Star Review

    Posted by on 27th Jan 2015

    Excellent fit and finish. Sound is now absolutely amazing on my 13 GT500 with the factory mufflers!

    The only tip I will give is to adequately torque everything up and then recheck after you heat cycle the system a few times. As with any bolted joint, it can loosen up.


  2. mrt off road hpipe 5 Star Review

    Outstanding product, easy install and quality is top notch. The car sounds incredible even with the stock exhaust. Very pleased indeed.


  3. Perfect fitment 5 Star Review

    Posted by on 20th Aug 2013

    Not very often that you buy an aftermarket exhaust kit and it fits 100% dead nuts perfect without moving anything around. But this one does. It is a very easy install and I recommend it.

    Only thing different I would have liked to see is a clamp for the H part of the pipes. The kit doesn't include anything for it. I used some ultra-copper and it worked as far as temperature,but the movement of the exhaust broke my seal. I put a little extra on this time, but may need to tack weld it first or just weld it all the way around. I am also a little anal when it comes to exhaust leaks and this probably wouldn't even be classified as an exhaust leak since it's so far back it won't have a bearing on anything except maybe sound.

    The rest of the kit is so good though I give it 5 stars anyway, I installed it by myself in about an hour on jack stands and the sound is an improvement.


  4. Great sound 4 Star Review

    Posted by on 13th Jul 2013

    I just got this installed on my 2012 GT500. Great sound with the stock mufflers. Easy to install and everything lined up perfect.


  5. Very nice product 4 Star Review

    Posted by on 22nd Oct 2012

    Easy to install. Another helping hand will speed the alignment of the catback and hpipe install.

    The pipe sizing and mandrel bends are nice and smooth and the o2's threaded in with no problems. Also, the rear o2's have enough slack in the wire to run them to the new h-pipe o2 location. Mrt has the rear o2's positioned about 4-6 inches further back vs stock no extension was needed on my 2011.

    4-stars
