KOOKS 2″ Headers – Background & Customer Review

If you have owned your car for more than a day or two, you have most likely heard to name KOOKS. That is because KOOKS is widely considered to be the best in aftermarket performance exhaust products.

So when we wanted to work with a brand to bring a 2″ (primaries) header to the community that not only fit perfect, but performed perfect as well, KOOKS was our only option.

KOOKS is by far the industry leader in the Holden community here in the states, that being said, it is a safe bet that if you gathered 10 owners with aftermarket headers, at least 7 of them would say they are running KOOKS. With that in mind, we wanted to come up with a solution that would be beneficial to the majority of our community.

Furthermore, with KOOKS being as wide spread as they are, other exhaust manufacturers have made it a point to create connection pipes to attach to their unique header collectors. These brand (SOLO & CORSA) are also some of the most popular cat back setups on the market. So we wanted to parallel ourselves with a brand that was usable with other, existing leaders of the industry.

In doing so, we ensured that these new 2″ Long Tube Headers will not only bolt directly up to your existing KOOKS X-Pipe, but also bolt up to ANY existing KOOKS compatible exhaust setups via their KOOKS connection pipes. In short, with these new headers you don’t have to replace the entire exhaust to upgrade your current KOOKS or compatible setup. Just the headers!

Recently, James House of JMG Motorsports was one of the first to get his hands on a set of our new 2″ headers, here is what he had to say about them.

“The craftsmanship of these headers is outstanding…”

“Install took about 2 hours… I never once touched a sledge to clearance anything.”

“…install was easy and the quality was top notch.”

Besides our new headers, JMG also installed a brand new SOLO 3″ Street Race Cat Back as well. This shows the versatility of these headers. They seamlessly bolt up directly to the SOLO cat back via SOLO’s catless KOOKS connection pipes.

*We will have some 1 7/8″ vs 2″ dyno results coming soon!

A rare overhaul of a 1-Owner Untouched G8

With the last MY (model year) G8 coming up on being 10 years old, it is very rare to find one unmodified and still held by its original owner. That being said, it is an even a rarer event to learn that this owner, after so many years of owning it in its stock form, is ready to heavily modify walks Troy Schnack.

Troy reached out to us looking to bring his G8 to its best possible version of itself. His build list seemed to grow daily, and in the end almost nothing was left untouched. All of the wrenching for this project was done by our friends Jason Posner, Kenny Thorsen and Derrick Rodrigues out of their Staten Island shop (aka: Sesame Street Racing).

Above and beyond the parts Troy got from us, he also purchased a CTS-V2 Brembo brake upgrade kit, some OZ wheels, a G8 Designs double din radio upgrade and some paddle shifters to start. Finished off by a full paint correction.

  • G8Only Ultimate DOD Delete Kit
  • RCR Spec Cam
  • RCR Tune
  • Camaro Trans Pan
  • Holley Valve Covers
  • LS3 160* Thermostat
  • VCM OTR Intake
  • Kooks 1 7/8″ Long Tube Headers
  • SOLO 3″ Catback w/Catted, Kooks Connection Pipes & 3.5″ tips

Quote from the owner:
“First day of daily driving, all the way from 15 mph zones to ~100 mph on the twisties. Everything is great, gentlemen. The suspension work puts that amazing amount of power to the ground perfectly. The brakes inspire confidence, and it is so damn flat in the corners. Wonderful!”

*Special thanks to Troy for allowing us to be part of his build! And a genuine thank you for you and your wifes service to this great country!

G8Only Exclusive Race Vents

Race vents, originally referred to as “Rally Vents” due to their popularity in international rally events, have become somewhat of a staple among consistant track goers and auto-crossers. Many tracks have rules in place that do not allow the driver to roll their windows down during events. In the summer months this can result in a very uncomfortable cabin environment. These vents allow drivers to vent their vehicles while staying within the regulations of their tracks. They can also be used while cruising to keep you comfortable without the front windows down.
