Product Description

Kooks Header & Catalytic X-Pipe Kit
These Kooks long tube headers for your 2005-10 Mustang GT features 304 stainless steel tubing, 1 5/8" primaries, and 2.5" 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 4.6L 3V Mustang! This kit also includes a Kooks 2.5" crossover x-pipe which is designed to connect your new Kooks long tube headers to your factory exhaust. This all 304 stainless crossover includes high flow catalytic converters along with all clamps and gaskets needed for installation!

What Sets Kooks Apart?
-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.

Quite simply...there is not a better header on the market!

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.

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

    Image uploaded by Timothy G. I bought this kit 2 weeks ago on friday, and it was at my door step that following Monday, so super fast delivery. I'll start off by saying the craftsmanship of these kooks headers and xpipe is awesome. Everything bolted right up without any problems, it was a relatively easy install as long as you have the know how. I am completely 100% satisfied with the power gains, and the sound this kit produces. I would definitely recommend this product to anyone you can't beat the quality and overall outcome your mustang gains from it. And as always I love shopping at latemodel they have always looked out for me with previous orders and have never done wrong by me, and I'll definitely keep ordering from them like I have been for the past few years.

    Yes, I would recommend this item to a friend!
