No matter how perfect an AMG comes factory, there's always room for improvement and a common area our Mercedes customers love to improve is the exhaust. Providing both performance and sound benefits, you can get the best of both worlds with one upgrade. The owner of this 2008 C63 came to us to receive those benefits, courtesy of Kleemann, with some long tube headers. Also on the exhaust to do list was a custom X-pipe and center muffler delete, done here in house.

With drivers side pipe removed from stock cat we test-fit the cat section to take measurements and found fitment issues with the headers.


The ball seat on the Kleemann header is too large for the stock socket to fit



You can see here how the socket will not sit on the ball correctly and this the clamp will not fit



This illustrates how far to the drivers side the exhaust is being pushed by the Kleemann header


Kleemann adapter pipe fitted to drivers side (where it belongs)


Kleemann adapter pipe fitted to passenger side to show that it fits the same


The Kleemann adapter pipe's socket is significantly larger than the stock one


The Kleemann adapter pipe's socket is significantly larger than the stock one, the stock pipe fits entirely inside the Kleemann one
