Ya I got it on but....Had to take the upper a-arm off and still had to persuade it with a hammer tapping the flange. It was so tight against the studs I couldn't line it up. When I put the flange on first it was even farther off. I'm just wondering how the hell I am going to get it off. On a good note my son likes the pipe. It really broadened the power band with a bit more bottom end than the LRD.
