IAMLeon I have the IPD stainless turbo exhaust on the back of my non-turbo 244 and it has a real nice note to it.
Exhaust shops usually want to just know whether they are dealing with a clapped out exhaust. Some will replace slip joints with flanges so want to know if they can weld to the existing pipe. I always ask if they do fixed price quoting, I got burned pretty badly once by shonky quoting.
