    Yeah, I keep going back checking their site, but it's acting weird, so I don't know what the problem is at Riss.

    My plan is to just turn a SS piece on the lathe that would match the tapered flare on the DP. Perhaps extending into the DP slightly (as you point out). I really don't want to restrict the exhaust flow at this connection by going inside the DP if I can help it. But yeah, I want a tight fit, so I'll see how this goes. This coupling would then be welded onto a short section just in front of the flex joint. I plan to use a stock OEM clamp as well.

    Thanks for your input Redbeard.

    The interuption in air flow at the DP will be small at best so long at the extension into the DP isn't too far. If you haven't had your stocker off the DP go ahead and pull it off and have a look at what MINI did. It makes good sense I jut wouldn't have made that piece of exhaust extend quite that far into the DP.

    How would two of these "Big Burtha's" be for twin megaphone exhaust tips? :D

    Maybe you could make some giant rear diffuser/exhaust tip 'thingy' of sorts :lol:

    I had shotgun pipes, that I really liked, but they were on a 1950 HD, hard tail, fully chopped with a 1/4 inch rake. Those might work for ya, if you like them. :Thumbsup:

    Now you're talking, but I'd tone down the yellow. I think just in SS is more subtle ;)

    OK....
    I need to order the SS flex joint. Seems to be at least two styles on the market. Looking for a little feedback on possible issues with failures of splitting etc.

    This design appears to have a double layer of the SS weave both inside and outside surfaces.

    This design has the weave on the outside and the corrugated bellows on the inside.

    Any insight / thoughts on one design over the other?

    Weave inside and out can be more long lasting and a little less disruptive of laminar flow, of course even a double weave flex can have faulty construction.

    Thanks Keith...
    I was thinking all the bellow corrugations running perpendicular to the exhaust flow was not ideal. The weave option is at something less than 90 degrees and seems to have a smaller step compared to the bellows, so probably less disruption to exhaust flow. I'll refine my search to the weave pattern. Any failures can be addressed by removal and replacement.

    Hey Chuck, hope this inspires you on your exhaust build. BBQ FTW! :cornut:

    I also think the exposed valve gear would be the bomb! :D

    Chuck

    There's a guy who bought a couple of 4" SS tips for his new Countryman. Had the old ends cut and new ones welded on. Obviously you're doing this from scratch but I think these look quite good. Not as good as the 6-foot long bazooka look, but decent nevertheless.

    Apparently from Prospect Muffler in Ft.L for $130 (installed). I think they look great
