BBK Stainless Steel 1-3/4" Long Tube Headers for 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020 and 2021 GT Mustangs, and 2012-2013 Boss 302 Mustangs.

Your all-new 5.0-liter engine is already delivering nearly double the horsepower of its 5.0L predecessor, but what if you could get even more horsepower and torque out of it? With the BBK Stainless Steel 1-3/4" Long Tube Headers (P/N: 16335) installed on your 2011-2021 GT or 2012-2013 Boss 302 Mustang, you'll see even more gains! 

This all-new rugged BBK header design is constructed with 1-3/4" CNC Mandrel-Bent stainless steel tubing and solid 3/8" laser cut exhaust flanges. Initial testing is showing gains of around 30+ horsepower with the high flow catted X-pipe. All BBK headers include a set of new gaskets, required hardware and detailed installation instructions for installation.

Features and Benefits:
- 1-3/4-inch CNC Mandrel-Bent Tubing
- 30+ Horsepower Gains with High Flow Catted X-Pipe
- Improved Horsepower and Torque 
- Ceramic Coated Finish 

*Ford changed the thread pitch on the header bolts midway through productions. 5.0L Mustangs made from March 2010-August 2010 require fine thread header bolts, 5.0L Mustangs made after August 2010 require coarse thread bolts. BBK includes bolts for either application. It is VERY important to make sure that you use the correct bolts--serious damage can be caused by using the wrong bolts.

Vehicle Fitment:
