Give your GTO the sound and polished finish you want

SKU: 24124200
The rear system and tips supplied together
The full 3" pipework is paired with Kooks polished oval race mufflers. The supplied 4" polished tips finish the visible upgrade, giving you the rear hardware and appearance in one cat-back purchase.
Fit it to the front system you are using
The cat-back connects to the factory OEM exhaust or matching Kooks mid-pipes. It is the 2005-2006 6.0-litre LS2 application, so choose it alongside the correct front connections if you are fitting headers as well.
