Well this weekend I was going to put in my u-bend delete peice but when I got the car up on a hoist I found two things I really didn't like. Someone had put in around a 1.75in diamater pipe about 2-3 feet long where the stock resonator is suppose to be. AND one of my rear sections after the Y splitter (on the drivers side) Looked like THIS.
But on the good side of things I replaced this with new pipe and put a 2 1/4in or so pipe in the section right after the downpipe replacing the horribly welded undersized pipe, the cat, and u-bend.
