| SKU | 27302400 |
| Application | Supported 2003-2006 Chevrolet SSR LM4 5.3L / LS2 6.0L |
| Material | 304 stainless steel |

| Collector / sensor fittings | Venturi collectors; O2 fittings |
| Required connection | Matching Kooks Y-pipe, separate |
| Installation change | Starter heat shield removed during fitting |
Upgrade the front exhaust on your V8 SSR with Kooks stainless long tube headers. They use 1-7/8" primaries, 3" outlets, O2 fittings and Venturi collectors for the 5.3- and 6.0-litre applications below.
SKU: 27302400
The headers cover the individual LM4 and LS2 application rows below. Their O2 fittings and collector arrangement are part of the header design. Fitting requires removal of the starter heat shield, so allow for that change when arranging your header installation.
A matching Kooks Y-pipe connects the headers to the rear exhaust. The catted Y-pipe linked below fits 2004-2006, so choose that route within those model years.
We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Talk to us to discuss the right tuning route for your vehicle.
For the 2004-2006 naturally aspirated SSR, the SSR catted Y-pipe provides the matching OEM rear route. Use that narrower pipe-year overlap.
