Alot of preformance companies sound promising at the moment, i wonder which ones are all just talk. I hope they will all do something for the Rx-8

GReddy brings up a good question I have.

I'm not a tuning buff, and I've never put a custom exhaust on my car. However, what do some of you have to say about exhausts that sound the best? I'm talking cat back, not just a muffler, or a tip.

A friend had a GReddy, I think it was the SP model, on his GSR a few years back. I thought the sound was fantastic. On throttle, or off throttle it had a nice throaty sound, yet while cruising with just a light bit of throttle resulted in almost no sound. So highway cruising wasn't a constant drone.

I've heard people really like Borla exhaust as well. Some Honda owners seem to really prefer Comptech.

Just curious what you all think.

I currently have the greddy SP 3inch piping catback on my FD and it is by far the quiestest aftermarket u can get. Obviously not the most free flowing for turbo application, but its still good.
