Kooks Trailblazer SS Headers w/Y-Pipe (2006-2009)

Kooks Chevrolet Trailblazer Headers are 304 stainless steel long tube headers that come with a lifetime warranty. Kooks builds all of their products to the highest standards, and these are possibly the absolute best headers you can buy for your Chevrolet Trailblazer. They feature O2 Sensor ports welded in to the pipes. With a proper tune, these headers are good for 20-35HP additional on your Trailblazer. The 1 3/4" headers work great for most engines up to 450HP. Beyond that it is recommended you upgrade to a 1 7/8" header for increased exhaust flow.

Kooks headers and X pipe are designed to be combined with or without the factory exhaust. You can add Headers and the Kooks X pipe and retain the rest of your OEM exhaust system or you can mix and match with other exhaust systems as long as they are compatible with the OEM system. For instance, you can use Kooks Headers and X Pipe on your C6 LS2 Engine, and have a Borla Catback exhaust. All Kooks products are designed to be compatible with the OEM system. You must always use the Kooks X pipe and Kooks headers to keep everything aligned back to the catback system or OEM system. As long as you use Kooks Headers and the X pipe, everything will bolt right up just as it would with the OEM system

When it comes to headers and exhaust systems, Kooks is an industry standard. Kooks Custom Headers has been building headers since 1962, when George Kook Sr. used his gas torch to build his first set of headers for the family race car. Being heavily involved in racing, his talents did not go unnoticed by all the local competition he would beat on the strip. With the help of George Kook Jr. President of Kooks Custom headers, Kooks has grown to a full fledge manufacturing facility in which hundreds of thousands of headers and exhaust systems are sold each year.

Why buy Kooks?
- Kooks puts in over 45+ years of race winning experience into each header system they produce.
- All Kooks Stainless Steel Systems come with a Lifetime Warrantee.
- Kook Headers yield the largest gain in horsepower out of any other header company. 
- Flanges are 3/8" thick and are made from 304 grade Stainless Steel.
- Ball and Socket construction leaves a leak free seal between headers and x-pipes.
- Kooks offer large diameter headers for high horsepower applications.
- Kooks utilizes a scavenger spike (patent pending) in each of their collectors.  These spikes increase the velocity of the exhaust and causes a vacuum effect for the exhaust gases to exit the cylinder heads, thus creating a large increase in power.

We also offer Jet Hot's header coating if desired. No real performance gains from Jet Hot coating but it does reduce surface temperature heat on the headers and help resist corrosion.

Differences between the two coatings are noted below.

STERLING SILVER is our brightest looking finish.  It comes out looking like a very highly polished aluminum.  This coating can withstand temperatures up to 1,300ºF and will reduce skin temps on pipes by about 300ºF.  It is a very low maintenance finish, easily cleaned with soap and water.  You can use any non-abrasive aluminum polish to bring out the shine if it ever gets dirty.  It will never turn blue or gold like chrome or stainless.  This coating works great on normally aspirated engines and any parts that need to have a show quality finish.

EXTREME STERLING is very similar in appearance to Sterling but not quite as bright.  It will hold its shine 200ºF higher and can actually withstand temps up to 1,700ºF.  This amazing finish normally cuts down about 400ºF on the skin temperature of pipes.  This coating is great for mild turbocharged or supercharges applications, or on pipes that have turned grey with other silver finishes.

Both of these amazing finishes are coated inside and out most of the time for better corrosion resistance, more heat reduction and better appearance.
