LTH Equal Length Long Tube Headers (FDLH00067T) - Ford Mustang 5.0L & GT350

The factory exhaust manifolds on the S550 and S650 Mustang prioritize sound suppression over performance, restricting airflow and leaving horsepower on the table. LTH Equal Length Long Tube Headers are engineered to do the opposite—freeing up exhaust flow, unlocking power, and delivering the aggressive V8 sound the Mustang platform is known for.

Designed and manufactured in-house in the USA, these long tube headers feature a precision equal-length design for an optimal balance of low-end torque and top-end horsepower. Finished in LTH’s exclusive Titan™ coating, they offer a durable matte finish built to withstand heat and harsh conditions. With a modular design that allows compatibility with OEM components, these headers are a proven performance upgrade backed by a lifetime warranty.
