I think this is getting a little out-of-scope here. While I agree cut-outs are great options I don't think this should be included. Mainly because the price and complexity of the system will be exponentially increasedNo one makes this, but I had one made. They make them for Neons. Mid-Pipe with the QTP Electronic Exhaust Cut-Out Placed Before a High Flow Cat. Maybe make it so you can run a pipe out behind the driver/passenger side tire. You wont throw a code because exhaust still goes through the cat and hits the sensor(not as much, but still reads properly). Also, there is no better exhaust system for a turbo car then no exhaust.
Do a search for Corksport and you should be able to find sound clips. They may even have a sound clip or two on their website (I can't remember). In my opinion it does not sound buzzy or like "garbage" at all. Regardless of what it sounds like I don't think we are in too much of a position to make demands.I'd buy a 3" turbo back exhaust so long as the tip wasn't massive and it didn't sound like garbage.
Fair enough, I suppose the pickin's are slim. Still, I don't want my MZP to sound like my neighbors Honda either. I'd rather custom make an exhaust if that's the case. A nice, somewhat deep tone is perfect.Do a search for Corksport and you should be able to find sound clips. They may even have a sound clip or two on their website (I can't remember).
