Lethal Performance 2011-2014 Shelby GT500 T304 3" Stainless Steel Offroad X-pipe

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 3" T304 Stainless Steel offroad X-pipe for the 2011-2014 Shelby GT500. Just like our offroad X-pipe for the 07-10 GT500 you can expect excellent gains and a more aggressive sounding exhaust. Our offroad X-pipe is made with 3" mandrel bent T304 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 15rwhp. We tested a similar 3" offroad X-pipe on our own 2011 Mustang GT on UPR's dyno and in 99deg temperature with 93 octane saw a 14rwhp increase over stock. That's on the stock tune, stock catback and stock manifolds.

Customer Reviews

Nice sound, great product, fits great Review by Tony
Just finished installing this X pipe to my 2013 Shelby. Fits just like OE, O2 sensors fit in the OE spots.

Loaded in my Lund tune (also from Lethal) car fired right up and idled nice. Sounded wicked when I revved it up a few times. Can't wait till spring and I can get it out for a drive to confirm my findings.

Everything should be fine.......very happy with fitment quality of this product. Thanks guys!!!!!! (Posted on 2/8/15)
