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" 16ga long tube headers for 2015-2017 Mustang GT are sure to give you the most horsepower and torque while fitting easier than any other header. The large primaries will flow much better than stock while winding down into 3" collectors and high flow catalytic converters.

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.

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

    4 Stars   Amazing product with perfect fit
    By on 3/27/2017
    Stainless works long tube headers are the perfect mod to compliment any cat back exhaust ( stainless works in my opinion ) and they sound GLORIOUS! the coyote 5.0 really shines with any long tube header and all provide roughly the same performance but there are so many options with stainless works that you cant get anywhere else.... only reason it got 4 stars from me is because stainless power is a sister company of stainless works so you get the same product but for much cheaper

    Yes, I would recommend this item to a friend!
