Is it possible to do this for a FWD MT? I looked under the hood and it seems there is enough room to get the CAT out by itself from the top, not under the car together with the downpipe. I spend like 20 min under the car and I was able to loosen all the bolts that hold the CAT and downpipe togheter.

What do you guys think, is this doable? Anybody did this already?

I don't feel like getting the downpipe off (in my case would be even more work cause it's welded to the exhaust - so that's one more problem)
