did you adjust the CAS? if you did not then do that if taht is done adjust throttle cable and set the timing. this is if you idle is a little jumpy so this might fix your problem. for the loud exaust problem sounds like a leak did you change all the exaust gaskets when you installed you exaust back on? try that and get back to us.
