Revamping exhaust system: Recomendations? Hey everyone, I need some insight with exhaust as of what I have now just isn't cutting it, rather more of robbing me. I've got a '99 Camaro SS M6 with AFR 205's, comp cams 232/234, FAST 90MM intake and tuning by speed inc. The exhaust, however, is what came with the car. I'm in minnesota, so I'm not worried about emissions laws. Right now the car has 1.75 super comp headers with the emissions still on with high flow cats, qtp electric cut out, with a flowmaster muffler. Piping seems to be 2.5 inch front to back. I would like to keep the headers and obviously the cutout. The rest however, can go. I hit 409rwhp with the cut out closed, and 422 with it open during a dyno run at the car craft summer nats this summer, and feel that is a weak link on the car. I welcome everyone's input because I need it. Thanks again for reading and any help you can give me.

At the risk of sounding uneducated, I have not heard of ORY before. Is that the actual name or not? What is the website. If not true duals, I take it everyone is pretty much running 3 inch, obviously no cats, 1 3/4 to 1 7/8 headers. Which brand is having the best flow rate of mufflers (I will NOT do magnaflow. I hated the catback system I had on a previous '02 WS6 A4)?
