Horsepower and Torque. Improve the performance of your 5.0L coyote powered Mustang by replacing those restrictive factory manifolds with a set 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 2" 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 2" 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 factory 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.

Product information notes these headers cannot be used in "emission restrictive" states... will my Mustang fail Missouri emissions with headers?

ScottS

  • These headers by themselves will not fail Missouri state inspection for emissions regulations however if you are planning to install these with a straight pipe setup that may change things. Please check with your local and state regulations for further information.

Will these prevent the transmission from being dropped when installed? I know some longtubes won't allow for the transmission to be dropped.

DavidP

  • Yes sir, these LTH long tube headers would be in the way of removing the the transmission. The majority of long tube headers out there will be this same way.

Will these fit with a magnaflow catted tru--x mid pipe? I now have this mid pipe connected to the stock exhaust manifolds.

Peck

  • They should bolt up, but you will not be able to use the existing cats with these LTH. If you're okay with running off road, these will bolt up with little to no modification.

    Wow

    Loudest header set up with off road x pipe. Headers clear no steering issues but will be a pain getting motor mounts in. You have to take the motor mounts, k memeber, and trans line to get everything in and the starter it's 100 worth it take your time and it will be a 2 person job. Tightening bolts on the headers is basically impossible will take literally hours
