We finally got rid of the exhaust smell in the cabin. The rear pipes are rather big being 63 mm Ø and it may be that the velocity of the exhaust gases are lower than when using the original tail pipe size. Anyway, we took off the tail pipe and installed a 45 degree exhaust tip just in front of each rear wheel and... no more exhaust smell! The exhaust note has changed slightly, more mellow and slightly louder at low speed, but not when driving on highways. Problem solved, but we may install original tail pipes later on...let's see if we can live with the side pipe look. Thanks to all for your valuable inputs. Cheers. /Finn
