Enjoy the V8 that makes your Trailblazer an SS
The LS2 is what makes a Trailblazer SS more than another SUV. Kooks 27202400 gives your exhaust upgrade 1-7/8-inch 304 stainless primaries and 3-inch Venturi collectors, with O2 fittings for the 2006-2009 6.0-litre application.
SKU: 27202400
Purpose-made headers and collectors
The 3-inch Venturi collectors connect to the matching Kooks Y-pipe, bringing the front of your exhaust together with parts made for your Trailblazer SS.
Allow for a proper installation
Professional fitting involves access around the engine, front driveshaft and crossmembers. Your installer can align the headers and Y-pipe together, then check wiring clearance and exhaust joints before you put the upgraded system to use.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your headers, complete exhaust and fuel. Talk to us to discuss tuning for your vehicle and the parts you are fitting.
Matching products
Add the Trailblazer SS Y-pipe for the 2006-2009 Trailblazer SS LS2 6.0 to complete the uncatted header-to-rear-exhaust connection.
