I'm looking at getting an exhaust, and I've tried to do some research, but there's not as much info out there as I'd like. I'm looking for a valved system that gives a fuller sound at idle/lower RPMs, still screams at high RPMs, and doesn't drone. I'm not looking for something super loud.

I've never had a Fabspeed exhaust, but people seem to like them. Clips sound good. GMG has an exhaust, and I had their exhausts on my 997TT and 991 GT3. They're usually pretty loud, but sound great.

Any thoughts on these two, or any other choices I should look at?
