Hear your Mustang V8 and enjoy the finished look
Change the sound and the rear view of your Mustang with Kooks 11406600. The 304 stainless axle-back combines mandrel-bent 3-inch tubing, polished oval mufflers and 4-inch polished tips for the listed GT, Boss 302 and GT500 applications.
SKU: 11406600
Fits at the original connection points
The 2-3/4-inch TORCA inlet meets the OEM exhaust position. No cutting is required, making this a focused rear-exhaust upgrade rather than a front-to-back replacement.
Take time with the tip alignment
Have the mufflers and tips aligned before the clamps are tightened. The fitting guide for the GT installation reuses the factory sleeve clamp; your installer should assess the retained joints on the actual car.
