My dad and I spent the afternoon mocking up the exhaust. I used 2 1/2" tubing and porter mufflers. As you can see from the pictures the mufflers are offset...the drivers side muffler would not fit in the cross member due to the master cylinder. Overall, I think that the exhaust turned out great. I still might move the passenger muffler to the same position as the drivers side. s I plan to finish the exhaust using 2" tubing out the back of the muffler via a reducer.
