I have a similar question - although I see this hasn't had a lot of replies....
Under hard acceleration and any other WOT driving, I hear my exhaust hissing (sort of under the passenger floorboard), and I feel like I'm losing power at the top end when the hissing starts.
I just got my X, and haven't even crawled under it yet (partially because it's cold outside, and I have no clean ground to do so). Previous experience tells me catalytic converter is getting clogged... Does anyone agree with that, and why or why not?
Second, are there any other threads, here or elsewhere, which can show me what would be involved in either replacing it with straight pipe or knocking the ceramic out of it?
I do not need to pass emissions in my locale - a rural area.
