Hey there,
I was digging around a year or so ago along the same lines. My exhaust project got put on hold (because I developed a more urgent "tire replacement" project that ate into my farkle budget!). However, I'll be looking again soon because I've noticed a bit of perforation on the underside of my nearly 20 year old stock can!
I had some emails from some guys at Wild Hair Accessories, who sent me pics of a Nikko high rise that looked nice. However, the pic was on a 4th Gen, so I'd want to make triple-sure before ordering. Here was the details of the dude I talked to:

I had a better feeling talking to some guys who were resellers of REMUS systems. Their details were as follows:
Knut Wagner & Frank Mullerauh

Good luck, and please let me know how you make out - like I said, this will be moving back up my priority list in a year or two (unless I grow to really like the rumble of a disintegrating can!).
