Re: 66 GMC Long to Short LS Swap

I finished welding the h pipe section and moved on to the back section. Got the mufflers mounted where I wanted them. Tried a few different pie cuts and bends to get clearance from the trailing arms. Everything is tacked up ready for finish welding once my flow meter and Furick Cup arrives. The slip fit on the Magnaflow mufflers is really crappy. The diameter of the inlets on the mufflers are too big so the fit is really sloppy. I cranked the clamps down but the mufflers still wobble. The gap is probably too big to weld up so I'm not sure how I am going to solve this



Still need to make a few hangers. Not sure if I am going to just dump the exhaust out past the axle or take it all the way out the back
