With not many good options out there for OB exhausts, I'm looking at fabricating one from some 3-inch mandrel bent tubing.

I have a 928 MS Y-pipe currently that I want to mate up to a new exhaust system. The problem is the 4-bolt flange that comes off the 928 Motorsports Y-pipe which mates up to the OEM 4-bolt flange does not seem to be a universal exhaust part.



When I search 3-inch exhaust flanges, invariably I only see "standard" 3-bolt flanges like this.



Anyone know a source for the four bolt flanges the are on the 928 exhaust?

Cut it off and go with a V-Band.

Yeah, I figured someone would recommend either v-band or cut and adapt a 3-bolt flange. Both would work. There are plenty of ways to skin this cat.

However, I really would prefer to keep the 928MS Y-pipe in tact with no cutting. At some point down the road I'll match up the new system to the new MSDS 16V headers that are coming out and the 928MS Y-pipe will have a lot more value as a used part if it remains a bolt on piece.

Call Tom at 928 International. I think that gasket is a part they stock.

I can't split them from my kits, I have no spares, sorry.

Prob have to have one made at a machine shop. Or make it your self. :-(

Call David or Garrity at Motorsports SLC as they make the Y pipes - he will be able to help you I am sure.

Thanks Roger. It must be a US thing. I've found a couple in Australia and Sweden, but they do seem to be pretty rare. I'll check with Motorsports SLC.

I'd still replace it with a V-band. They are the only reliable way to seal an exhaust joint and much better than any flange.
