Horsepower and Torque. Improve the performance of your Shelby GT500 Mustang by replacing those restrictive stock manifolds with a set 1-7/8" LTH Long Tube Headers for an increase in horsepower and torque. LTH headers were developed to give you the best balance of low end and top end power when installed with a matching LTH shorty Mid Pipe.

Stainless Steel Construction. LTH Long Tube Exhaust Headers are manufactured in the USA from mandrel bent 1-7/8" diameter 304 stainless steel tubing for superior airflow, durability and corrosion resistance. They are completed in LTH's Titan™ Uniform Satin Finish for great looks.

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.

Required Upgrade. For proper operation and maximum power potential these Long Tube Headers will require reprogramming the vehicles computer. AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles ECU for proper operation.

Application. These 1-7/8" LTH Long Tube Headers are designed to fit the 2011-2014 Shelby GT500 Mustangs equipped with the Supercharged DOHC V8 engine. LTH long tube headers will require the use of a LTH shorty Mid Pipe in order to be installed properly (see options above).

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

    Perfect Fit !!

    I researched several Header Brands prior to making this purchase. I always do my homework !! The biggest complaint I hear is issues with the Steering Shaft rubbing. NOT A PROBLEM with these babies. There is plenty of room between the tube and the shaft. Fit and Finish also perfect. no Leaks, Sound and Perform AMAZINGLY!! Lots of room around Starter as well !! Have them mated to an LTH offroad X pipe and Corsa Sport Mufflers, along with 2.4 upper, 10 Lower, JLT Cold Air, Ford Racing Single Blade TB, 373 Gears, McLoed RXT and a BAMA Tune to name a few. The car is a BEAST!! Had these installed at my local FORD dealer, a little pricy, but what the heck!! If your looking for Performance, Fit and Finish and a Great Sound, Look no Further. I could not be happier and my GT500 is even more of a Beast now!!
