Add horsepower and torque that pairs with the throaty exhaust note to your 2015-2017 Mustang 5.0 with a set of Kooks 1-7/8" headers. These Kooks long tube headers for your S550 features 304 stainless steel tubing, 1 7/8" primaries, and 3" collectors with O2 bungs welded in. Kooks builds all of their products to the highest standard, and these are quite possibly the best long tube headers you can buy for your 2015-2017 Mustang! This kit also includes Kooks off-road extension pipes which is designed to connect your new Kooks long tube headers to your factory exhaust. Quite simply, there is not a better header on the market!
- Kooks is known for building the best high-end consumer headers in the world. This header is constructed with the below high-end features!
- Tig welded with all 304 (aircraft grade) mandrel bent stainless steel construction
- Integrated venturi merge spike for better savaging and less collector turbulence
- Primaries blended into the flange for better flow
- Leak Proof Ball Flange collector for trouble free ownership.
- Each primary tube is one continuous piece of tubing. Some competitors weld several pieces of tubing to create one primary, which is a weaker design.
It is recommended that you buy a custom tune after installing a set of longtube headers.
You're going to have a decision to make when it comes to selecting a new set of headers for your Mustang… shorty or long tubes. Well, I'm going to go ahead and put it out there before we get into the differences.
We all know that factory manifolds are restrictive and not the best for making power. ... more
