Product Description

Kooks 1-3/4" Long Tubes
Add horsepower and that throaty exhaust note to your 2015-2018 Mustang 5.0 with a set of Kooks 1-3/4" headers. These Kooks long tube headers for your S550 Mustang features 304 stainless steel tubing, 1 3/4" 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 2015-2018 Mustang! This kit also includes header gaskets, header nuts/bolts, and Kooks off-road extension pipes, which are designed to connect your new Kooks long tube headers to your factory exhaust. Quite simply, there is not a better header on the market!

Why Kooks?
-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.

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 2015-2018 Ford Mustang GT
