Hmmm, seems I may have been beat to the punch on the x pipe idea on a 911,
Available from Pelican no less!, major difference here of course being the fact that I'm using 2.5 inch pipe and on my final design a true performance muffler. I've selected four candidates for mufflers all with excellent flow ratings so it's going to come down to sound quality. Can anyone confirm that the Manta exhaust has a true X pipe crossover configuration? Or are the pipes just really close together? I noticed the Manta has three bolt flanges with smaller mufflers on their side, could this actually be a pic of a 912 exhaust and not the 911 version? I doubt there's room for the mufflers on their side on a 911 unless they're very narrow.
On another note, I can't wait for a chance at the chassis dyno! This prototype definately has more midrange than the Flowmaster I had on the car, I took the exhaust off this morning for some minor tweaking of the fit and decided to pop the flowmaster back on for comparision, it just doesn't have the midrange pull of the X-pipe.
