Finish your Kooks GT350 system with a full 3-inch rear section
Extend a matching Kooks X-pipe and OEM-connection installation into a full 3" exhaust with this GT350 rear section and mufflers. The system retains the bumper-mounted factory quad tips, keeping the rear appearance while changing the exhaust section underneath.
SKU: 11546300
For an existing or planned Kooks system
This rear section converts the matching Kooks X-pipe and OEM connections to a full 3" exhaust. It requires that front arrangement and does not connect directly to the unmodified stock exhaust.
Keep your factory quad tips
The bumper-mounted factory tips remain in place. This listing supplies the rear section with mufflers, making it the next component when completing the appropriate Kooks exhaust rather than a complete header-to-tip package.
