Product Description

Stainless Works Quality
Stainless Works is a leading name in longtube headers for Coyote powered Mustangs! If you're looking for the best fitting, best sounding and best performance gaining headers; then look no further than Stainless Works. These 1-7/8" long tube headers for 2015-2017 Mustang GT are sure to give you the most horsepower and torque while fitting better than any other header. The large primaries will flow much better than stock while winding down into 3" collectors and off-road lead pipes. Off road exhaust is for track or race use only.

Performance Connection
Stainless works has created the Performance Connection exhaust. This type of connection ensures a full 3" exhaust from header collectors to tips and doesn't reduce down. Because of this type of connection, this header kit requires the use of part number STW-M15CB3.

Installation/Tune Note
-Installation of long tube headers will require custom tune to prevent damage to your vehicle. If you already have a custom tune on your Mustang, please consult with your tuner prior to installation and operating your Mustang.

-Fits 2015-2017 Mustang GT using STW-M15CB3 catback.

-Legal in California only for racing vehicles which may never be used upon a highway.
-It is illegal to remove a properly functioning catalytic converter.
-Not Legal for sale or installation on vehicles operated on public roads in California.
