Also I don;'t think they sold the cab in Canada. So if you get one here, it’s an import. There are about 5 or so up here that I have seen go through the sales.
Are you located around Chicago? If yes then I would try AMS, Strictly Modified, Dean’s Performance, or CPT. Dean’s Performance specializes in Fords but he does tons of BMW stuff.
Titanium catback for B6 S4 for sale here. Probably much cheaper than a custom TI exhaust and you can try it to make sure the sound is worthwhile before you go custom.
I think the fact that nobody has even heard of them tells you something buddy… Kline Innovations do Titanium as we’ll don’t they… I had a good look round there site and them manifolds for the RS 5 look like works of art…
