Increase Power And Performance. Add even more horsepower and torque to the rear wheels of your GT or GT500 Mustang by eliminating those power robbing catalytic converters with an LTH Off-road shorty X pipe for power you can feel throughout the RPM band. An LTH Off-road X pipe when combined with a set of LTH Long Tube Headers will greatly improve your V8 Mustang's exhaust flow to increase horsepower, torque and overall performance.

Race Car Growl. The LTH Off-Road X-Pipe not only increases the power of your Mustang, but it also changes its sound as well. The modern X crossover design of this LTH Mid Pipe will add a loud raspy, race car style growl to the sound of your exhaust. While being louder than stock, the sound is not overbearing or obnoxious.

Deletes Factory Cats. LTH designed their Off-Road X-Pipe to eliminate your Mustang's restrictive stock catalytic converters. Because of this, this X-pipe is not CARB certified, therefore it is not legal for use in California or any other state adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

Stainless Steel Construction. LTH proudly designs and manufactures their X-Pipes right here in the USA. This X-Pipe is constructed from mandrel bent, 2.75" diameter 304 stainless steel tubing for its durability and long lasting corrosion resistance. This LTH Off-road Mid-Pipe features a merged "X" crossover for superior exhaust flow.

LTH Titan™ Uniform Satin Finish. Titan™ is LTH's unique proprietary process that produces a bright uniform satin finish over the entire part to eliminate the ugly discoloration from welds, heat, and scratches that are encountered during manufacturing; making it the perfect exhaust finish for high end show cars. Not only does the process create a show quality finish, but it also strengthens the stainless steel to eliminate microscopic sharp edges created during welding that could, if not removed, become tears and cause the product to fail.

Application. This LTH Shorty Off-road X-Pipe is specifically designed to fit the 2011-2014 GT and Shelby GT500 Mustangs with LTH Long-Tube Headers installed. Intended for off-road use, does not include catalytic converters.

Technical Note: This LTH product is intended for off road use, and is not legal for use in emission restrictive states.

          Great product!

          Got this x-pipe because I wasn't ready to go long tube headers yet but wanted more sound and wow did this do it! The only downside is my neighbors not being to happy with me!
