I bought some Hawke tail pipe units for my 2010 TDV8 and they fouled with the rear balancer masses. You will probably find that the clearance on both sides of the car is different I had around 5mm on one side and 10mm on the other. Niether is enough to stop the tail pipe units touching the balancer masses.

My view is unless you are prepared to get the exhaust system "bent to clear" then dont buy the tail pipes as they will foul with the balancer masses.

Looking at a sport from the rear most of them have the left hand side pipe a little bit lower than the right hand side More noticeable on the pre 2010 models.

Sorry to hear that Meiang.

My system is fine..no touching of the harmonic weights at all... RRS gone
