Carnewal GT Exhaust Modification for 987 Cayman/Boxster



Cantrell Motorsport has the exclusive US license to perform the Carnewal GT muffler modification.

We have Carnewal GT exhaust available for the 987 Cayman and Boxster which is a reworked original exhaust, modified in our workshop. Everything looks 100% original on the outside but the internals are changed to a better flowing, less restrictive exhaust.

It looks just like stock on the outside but the internals are changed to a better breathing, less restrictive exhaust. The result is a louder and deeper sound with no resonance. On the cars with Tip gearbox, there is no droning between 2200 and 3000rpm.

This exhaust does not trigger check engine lights and is not giving problems with emission checks during  technical inspections.

*Note* Some early 2005 models are not able to be modified. Please contact us for details to make sure your system can be modified.

When ordering, please note year, model and mileage of your vehicle in the NOTE section on the Checkout page.
