Check out the awesome comparison article SVTperformance did between the Lethal Performance X and H-Pipes for the 2011-2012 GT/BOSS.

NOTE: We highly recommend running this pipe with a custom tune. If you run this pipe without one not only will the car throw a check engine light but you won't fully benefit from getting rid of the cats. So not only does the tune turn off the rear o2's to prevent the check engine light from coming on it will also turn off the Cat Over Temp protection feature in the tune. That feature dumps fuel in order to cool the stock cats. Since the cat are no longer used with this pipe that feature if not turned off will only richen up the air fuel mixture and result in sacrificing some performance.

Lethal Performance is proud to release our exclusive 3" offroad H-pipe for the 2011-2014 5.0L Mustang GT. Just like our offroad X-pipe for the 2011-2014 5.0L Mustang GT, you can expect excellent gains and a more aggressive sounding exhaust. Our offroad H-pipe is made with 3" mandrel bent aluminized steel and is a direct bolt-on requiring no cutting or welding. Installation should take you less than 1 hour using simple hand tools. Just remove the stock catted H-pipe and install our 3" offroad pipe and you can expect gains of up to 14rwhp.

Excellent Sound Review by Bryan
I had this product installed at a local shop and it sounds great. After doing my research on sound and what I want the H-pipe seemed to be the best fit for me, very deep and throaty sound. If you buy this product make sure you get the Jon lund tune because I've had it since i put 1000k miles on my car and It's by far the best tune you can get. (Posted on 5/16/16)
