BBK Chrome 1-3/4" Long Tube Headers for all 2011, 2012, 2013, 2014, 2015, 2016, and 2017 GT Mustangs.

BBK Research and Development department developed these headers (P/N: 1633) with one thing in mind--getting even more horsepower and torque out of the all-new 5.0 liter Mustang that is already putting out nearly twice the horsepower of its 5.0 predecessor!

This all new rugged BBK header design is constructed with 1-3/4" CNC Mandrel-Bent 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--and BBK will have an off road version available for even more horsepower gains. It features a full chrome finish. All BBK headers include a set of new gaskets, required hardware and detailed installation instructions for installation.

*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.

Tech Tip: All 2015-2017 GT Mustangs will require either P/N: EX1816 or P/N: EX18160 for installation. In addition, 2015-2017 GT Mustangs must use the BBK Front 12" O2 Extension Harnesses and Hardware Kit (sold separately) P/N: O2H6.

Please Note: These headers are NOT compatible with RHD (Right-Hand-Drive) Models.

Please Note: Will NOT fit 2018+ GT Mustangs.

Would you be able to intall this to factory with out getting the o2 extensions and without getting the midpipe? Is it going to fit?

Asked by: ChrisZ
No, you would need the extensions and mid-pipe to fit properly.

Does this part include the o2 sensors?

Asked by: Dnvn1996
It does not, you have to reuse your existing sensors.
