s40 Exhaust Specs
 

I'm buying a new s40 and want to install a universal 'Internal Disc System' Supertrapp exhaust. To determine which of the 5 universals will fit I need the exhaust inlet diameter, exhaust outlet diameter and the length of the stock muffler.

Unfortunately nobody (including the dealer and Supertrapp themselves can tell me what these measurements are!)

Can anyone please help?

Mahalo!
