Let your SSR sound as distinctive as it looks
Give your SSR a coordinated front exhaust upgrade with Kooks 1-7/8" long tube headers and a Performance-catted Y-pipe. The kit covers the listed 5.3-litre LM4 and 6.0-litre LS2 applications, connecting to the OEM rear exhaust.
SKU: 2730H420
A package for both SSR V8 applications
The stainless headers use 3" collectors and the supplied Y-pipe has 3" front pipework with an OEM outlet. The fitment table separates the 2003-2004 5.3 from the 2005-2006 6.0, keeping the year and engine details easy to find.
Retain a compatible rear exhaust
The OEM rear interface lets a compatible cat-back remain in place. The supplied Performance cats suit naturally aspirated engines, so choose a different catalyst arrangement if your SSR is running forced induction.
Fitting your exhaust
Installation includes removal of the original starter heat shield.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Contact us to discuss the right tuning route for your vehicle.
