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 5.0L Mustang GT. Just like our offroad x-pipe for the 2011 5.0L Mustang GT you can expect excellent gains and a more aggressive sounding exhaust. Our offroad Hpipe is made with 3" mandrel bent T-304 Stainless 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.

SS Off-Road H Pipe Review by Jim
The quality was very good, nice welds and craftsmanship, Deeper tone that really brought out that Muscle Car sound.

Overall a great product I'm happy with it, and sounds amazing, but the install time for a individual isn't going to be a hour. You will need a 2nd person to make this install less difficult if your doing this yourself. Soak your factory bolts with PB Blaster before you start removing them it makes life easier later on in your install. I'd buy it again! (Posted on 4/9/17)
Worth it Review by JOSHUA
I can't say anything bad about this H pipe fit is perfect and the sound omg the sound I have a magnaflow gt500 quad catback on the car and the volume on a scale of one to 10 is a 20 my car has that deep rumble you'd expect for a v8 (Posted on 3/12/17)

Great Product and a worthwhile upgrade. Review by Mike
This off-road stainless h-pipe is well made and very easy to install. Used a jack and stands in my garage working by myself. As a tip the factory header exhaust nuts can be tough to break loose but spraying them with a breakaway fastner lube and letting them soak definitely helps. I also would suggest some long 3/8 extensions and a universal along with a breaker bar, that should do the trick. Absolutely no leaks and the fit and finish is outstanding. Currently using a Steeda Cold air kit with off road tune and will be trying a Lund tune for comparison shortly. (Posted on 9/28/14)
