Very cool build! Excited to see the final one!
Love the dual center exhaust. Would make my Roadster look a bit more like my Cayman if you ever offered that as a part!

Pretty tough to run a center exhaust with the gas tank right in the way. I do however seem to remember some talk here about running a crossover pipe just behind the tank for a dual exhaust with exits on either side of the gas tank. I don't recall that ever coming to frutation. I think JT68 was going to experiment with the concept.

Yes, we built some prototypes, but no one ever asked for any, so we dropped it. These really don't even need a rear resonator can which makes them less expensive to build than our standard rear resonators (either cone or twin pipe)
Since these are die formed bends in 2", there is almost no restriction-highly efficient, not loud. I did not really want a "Cayman"look. Lately, we have built some bigbore systems and twin tips for SRdet cars. I'm sure those will surface on some build photos too!

These are 2" NA systems.
