    Horsepower and Torque. Improve the performance of your 5.0L coyote powered Mustang by replacing those restrictive stock manifolds with a set 1-3/4" LTH True 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.

    Modular Design. LTH engineered their 2011-2014 GT exhaust using a unique "modular" design that allows you to upgrade one section of your exhaust at a time - including the headers, Mid Pipe, over axle pipes or axleback. LTH True Long Tube Headers are longer than other brands so called long tube headers so that no special Mid Pipe is required for installation. They will bolt right up to the factory H-Pipe or any "stock length" Mid Pipe including LTH's very own catted or off-road versions making them a true modular replacement.

    Stainless Steel Construction. LTH Long Tube Exhaust Headers are manufactured in the USA from mandrel bent 1-3/4" 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 1-3/4" LTH True Long Tube Headers are designed to fit the 2011-2014 GT Mustangs equipped with the coyote 5.0L DOHC V8 engine. LTH long tube headers can be installed with the stock Mid Pipe or one of their LTH shorty Mid Pipes (see options above).

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

      Sounds wicked, but read first!

      Hey all so these headers are wicked! They sound amazing, they look amazing and the finish is so smooth! However there are a couple things you wanna know going into this installation, 1. The install took 10-11 hrs and was not fun at all, but it was worth the struggle in the end. 2. You will need to get some ceramic wrap for the starter wire, it’s so close to the starter that it’s going to melt it after some time. 3. If your using the stock midpipe like I am you wind have a spot for your “aftercat” o2 sensors. There’s only one o2 bung on each header collector and that’s it. I’ll be ordering the catted x-pipe after mid summer after I have had my fun with the terrorizing everyone in town, it’s sooo sooo loud like in cabin if the car, not bad. Outside in the backside ear piercing lol! I love it have gotten a lot of compliments! I posted up some pics of the install, wish I could post a video too :)
