better access to the fasteners that attach the cats to the turbos? I read the write-up in Tech by Damon for gutting the cats, and the engine stayed in the engine compartment, but OMG I can't even begin to imagine how you access the fasteners at the top of the cats!
I REALLY wish I would have just gone ahead and pulled the engine out. It's not like I don't have all the tools to do it :(
