Dynamax Super Turbo
Yes, I am running the Dynamax Super Turbo 17748, 2 1/2" pipe, 20" long, with the PYPES SGC10 X-Pipe system. I had the PYPES Race-Pro mufflers on it for a few days, but it was a little louder than I wanted. I am very pleased with the way it sounds now.
My car at present has no upholstery except the seats, it's like a tin can in there (mark can attest to that!), but there's very little exhaust noise in the car. In fact, at interstate speeds, I can cut the engine and barely tell a difference. Most of my noise is the tires on the pavement.
I haven't heard it from outside the car under acceleration. I need to get Mark over here and let him drive away in it before I could say anything about that. But from inside the car, on hard acceleration, you can hear the power then, but it's not an "overpowering" roar.
With the X-pipe and longer mufflers, I did have to alter the eBrake hardware. I can give details if you want.
