Boost Your Mustang's Performance. The road to getting the most out of your Mustang begins and ends with MBRP aftermarket parts and upgrades. These 1-7/8-inch Long Tube Headers provide maximum air flow, resulting in both performance gains and a powerful exhaust tone. When paired with other MBRP exhaust products, MBRP Long Tube Headers can deliver gains of up to 44 HP and 28 ft/lb of TQ over your stock system.

High Quality Construction. MBRP uses only the highest quality components and fabrication methods. These T304 stainless steel Long Tube Headers feature 1-7/8-inch mandrel-bent primary tubing that provides paramount durability and the smooth 3-inch merge style spike collectors ensure that airflow isn't disrupted. The 3/8-inch head flanges have been painstakingly laser cut to fit your 5.0L perfectly.

Intuitive Modular Design. Crafted with a unique modular design, these MBRP LTHs allow you to choose the exhaust combination that best fits your build. The highest gains have been seen when pairing these Long Tube Headers with an MBRP H-Pipe and MBRP Cat-Back System.

Installation. Designed to re-use your factory GT header gaskets, this set of two Long Tube Headers by MBRP include the necessary hardware to install them onto your 5.0L Mustang.

Recommended Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. The MBRP 1-7/8 Inch x 3 Inch Long Tube Headers are specifically designed to fit all 2011-2020 GT 5.0L Mustangs and requires a MBRP 3-inch mid-pipe and cat-back for installation. For left hand drive models only.

Application Notes. For 2020 Ford Mustang GT models ONLY, a Ford Front Driver Side Oxygen Sensor will be needed to complete installation. This sensor is of longer length, you can easily use that sensor as a substitution for the shorter OE passenger side oxygen sensor during installation.

          Worth every penny

          I bought the kit with the off road h pipe. Had professionally installed but I helped with most of it. If you get the please read the instructions, the hardware supplied replaces the studs, and I started putting the stock ones back in until I realized they are too long for these headers. The bolts that replace the studs are shorter and have a 13mm head, which is extremely hard to get a wrench on it on the driver side. Anyway it took us 13 hours on a lift with all snap on tools, but in the end it was worth it. The finish is excellent, the fit is great. The sound and power bring a smile to me every time. Got a pbd tune and an 18 manifold when I did this and it’s a beast compared to stock

          Super aggressive deep tone !

          These long tube headers really made the 2015 GT really have a deeper rumble and really opened up to make the mustang breathe and have better air flow. Installation was kind of long but make sure everything is sealed right and bolted on right from the engine to the Cat back exhaust. Overall it gave a nice tone and increased the horsepower and you can really feel a difference after installing these headers.

          Must have for GT owners

          With this MBRP long tube headers, your car doesn't feel like a stock car anymore. I mean these headers bring so much out of your pony that you will feel that each penny spent on it is well worth it. Great product.
