Found a Lower Price? We Will Price Match on These Headers!- If you Have Questions, Call us @ 443-730-9428!

Effective 04/01/15 Kooks has discontinued the 1 3/4 version of the G8 header. This is due to low demand, and the very small difference in performance between a 1 3/4 headers and 1 7/8 headers on a stock G8. The 1 7/8 version of course better supports mods beyond stock. 

MarylandSpeed is excited too offer Kooks new exhaust system for the Pontiac G8 GT! This new system includes Long Tube Headers (1 7/8), High Flow X-pipe (catted or off road), and optional axleback exhaust. As always, we are excited to offer great package prices, discounted coating, and unmatched service.

 

Long Tube Headers-

These 304 stainless steel long tube headers are for the 2008+ Pontiac G8 GT. Kooks builds all of their products to the highest standard, and these are possibly the best headers you can buy for your G8. They feature 1 7/8 primaries, and 3 high velocity merge collectors with O2 Bugs welded in. 1 7/8 is our most popular size for the G8 because they support a stock application with no real difference in performance vs. 1 3/4, but also allow room to grow. 

 

High Flow X-pipe-

 

Your new headers are much longer than your factory manifolds. Because of this, you must purchase a new, shorter, Kooks X-pipe to connect your new headers to your factory/aftermarket exhaust. The G8 Kooks X-pipe is a high flow 3 x 2.5 full length design. It can be ordered with high flow cataytic converters (PT#6711-CX) or off road style without cats (PT#6712-OX). These X-pipes are the best design on the market and feature flex joints to reduce any harshness or drone from the G8's MDS system. Both are made of 304 stainless steel and engineered to the same high standard as Kooks other products!

 

Have a Corsa Catback?

 

We now offer Connection pipes that will bolt right up to your catback without a Kooks X-pipe! Selectable in the dropdown above, these pipes are available both with, and without cats.

Have a Solo Catback?

Optional Solo Performance “Kooks to Solo” High Flow Cats Specs:

  • 200 cell stainless steel spiral wound design. This design is long lasting, ultra-high flow, and completely stainless inside and out.
  • Converters are far overrated for the car at 6.0L per side. That’s 12.0L of cleaning ability.
  • Includes a special design stainless steel 3/8” thick front flange.
  • All mandrel bent pipes, O2 bungs, and welds are stainless steel.
  • No CEL or engine lights.
  • Solo O2 extenders (supplied) are required in the rear O2 bungs.
  • Works with G8 Mach, Mach-Shorty, Mach-Balanced and Mach-Shorty-Balanced.
  • 100% BOLT ON! 100% STAINLESS- one small cut on each side and then use the supplied band clamps! No welding necessary!!!
  • Available as off road also!

 

Axleback Exhaust-

Buy as a Package and Save!

 

This Kooks header/X-pipe system will bolt to your factory axleback/mufflers just fine. However if you want a more aggressive tone, Kooks also offers an all 304 Stainless Axleback system (PT# 6718). This 2.5 System features Kooks own quad core race mufflers. These mufflers product an agressive yet refined tone. The system ends beautifully with 4 double wall oval tips that look right at home in the G8's rear valance! If you buy the complete system from MarylandSpeed (Headers, X-pipe, and axleback) you get an awesome package price!

What Are Ultra High Performance Green Catalytic Converters?

Kooks offers a standard High Flow Race Catalytic converter for all applications. This is the same style high flow race converter that every other header manufacturer offers. Without a tune, the Standard high flow converters throw check engine lights in almost every application they heat up and flow differently than the stock cats. To solve this, and provide a more durable converter, Kooks now offers connection pipes with what they call Ultra High Performance Green catalytic converters. These new green cats from Kooks use a special design that uses remium materials never before seen in a aftermarket converter to flow at a very high level, while not throwing check engine codes (for the vast majority of customers). In the testing thus far, 98% of customers did not get a check engine lights with the stock tune. Those who did get lights were at a performance level where a tune would be required anyway. These Green cataytic converters have also proven more durable due to their premium design/materials, and are recommended for extreme HP or supercharged applications. Please note connection pipes with green cats do cost more due to the premium construction (for instance they include more platinum than most cats), and are special order.

This does not effect the fact that long tube header setups are sold for off road racing use only. Any time you remove functioning factory catalytic converters from a car, you are breaking emissions laws.

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!

 

Includes O2 Extenders, along with all bolts and gaskets needed for installation (2 stock O2 wires are reused during installation).

 

HEADER COATING-

For years we have been dedicated to proving our header customers with the best header coating options at affordable prices. For nearly a decade we offered Jet Hot as our main promotional coating. Unfortunately, under new ownership, Jet Hot discontinued their dealer program resulting in everyone now paying retail price for coating. In response, we have lined up two great peer coating company's offerings for our customers that will allow us to offer the same low prices as before. The coatings all the companies use are very similar, and the main difference is the time an attention put in to doing the job right. Airborn and Calico perform the coating process at the same, or higher level than Jet Hot.

  • Airborn Coatings has a history that goes back as far at Jet Hot. Their owner is a chemist who had a hand in developing the originial ceramic coatings. Airborn offer the same great 1700 degree inside and out silver coatings as Jet Hot with a great warranty to back it up. It is now by far our most popular coating option.
  • Calico Coatings is a company from the heart of race country in North Carolina. They are Kooks preferred coater, and offer not just header coatings, but a wide range of engine and industrial coatings.
  • Jet Hot Coatings will still be offered for those who demand the name, however it will be at the new, higher price.

Things to know about these coatings -

  • Airborn And Jet Hot coat their headers inside and out. Calico only coats the outside of the header.
  • The silver/chrome look coatings we sell (Airborn 1700 Silver Jet Coat and Calico CoolKrome) are the most popular and durable selections. Silver looks good on everything, making an awesome color choice. In terms of durability, if you overheat a colored header, it will be permanently discolored. If you overheat a silver header, it will lose it's shine in the area overheated, but the shine can be brought back by simply using wheel polish on it.
  • Calico's CoolBlack II coating is the best looking black coating we offer featuring a nice satin finish. Airborn's Flat Black has a gritty texture and appearance.
  • Coated header orders are not cancelable. Coated headers on average take 2-4 weeks with colors taking longer than silver coatings.
