Thanks for all the comments and sugestions,
Damage: I called the Mercedes dealer and asked if they did sell the g63 in SA as per European specs, I got a very short "of course we do" I think he thought he was getting a sale when he answered the phone
The problem is no longer the exit points it will be the noise, it seems no one has successfully made a set of side pipes that comply without stuffing them full of dirty laundry and chicken wire and anything else that will fit up the pipe, not really my cup of tea.......I would like to know your trick Damage....
I have had a long conversation with my engineer, his suggestion was "save yourself some grief and probably money, modify the fuel tank or new one, put an under car system in, regency park inspectors will be happy and so will you be"
So I have ordered some cheap shorty block hugging headers , the NEW stainless tank will be ready next week, then back on to Low Tow to exhaust technology
One step forward.............
Cheers
Kent
