Product Description

Kooks 1-7/8" Long Tubes
Add horsepower and torque that pairs with the throaty exhaust note to your 2015-2018 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 Mustang! This kit also includes Kooks "green" high-flow catted 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!

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

    Long tubes do make more power and torque versus a shorty header. So why would anybody ever purchase a shorty header? more

    5 Stars   BEST SOUND EVER!!!
    By on 7/3/2015
    I only had the JLT CAI with a SCT tune and the Borla Sport catback with X pipe and thought that was loud. After installing these, it was way LOUDER and am glad i bought these. BEST sound to my ears and love the product. At idle its nice and quiet but once you get to 3 RPM's, you hear that coyote howl!!!. Instant notice on the acceleration and on lower RPM"s and definitely a much smoother ride from low RPM's all the way to redline. If your looking for headers and want the best, THESE ARE IT.

    Yes, I would recommend this item to a friend!
