Mustang BBK Long Tube Headers 1-3/4" Chrome GT 2011-2012

BBK Part Number: 1633

BBK Chrome 1-3/4" Long Tube Headers for 2011-2012 Mustang GTs.

BBK R&D department developed these headers 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. Features a full chrome finish.

All 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.
