Sometimes you can use your brakes fine in a corner, it just depends on your line and how hard you're attacking it. But until you figure out when you can and can't, don't. And you need a real light touch as well.
For the exhaust, I had a CCC road legal stainless end can which was very good for what it was, but I'd not buy another- smart option is a race can with a removable baffle now I think. If I was in the market for a single slip-on, I'd get a Remus Revolution. If I was in the market for 2, I'd get a rene high level
