First off, I have been having an awful exhaust leak noise coming from my wastegate for some time now, and after taking the wastegate apart, Im pretty sure its because the gasket connecting the wastegate to the pipe isn't making a seel around the wastegates plunger. So does anybody know where I can get one of these gaskets?

Secondly, Im pretty sure the catalytic converter on my car is blocked with crap from normal driving and from when it was running rich. I live in Montana so emmisions aren't a problem. Can I take off the catalytic converter and put on a midpipe or can I just cut out the combs in my catalytic converter, what do you guys think? There is a midpipe on rx7.com for $99, would this work? http://www.rx7store.net/product_p/midpipefd3s.htm It says only for use off the road, but I dont know if that is because of emmisions laws or not? Also would this make my car way too loud? Thanks guys
