Spent some time on this yesterday. I opted to cut up my old unmolested muffler so I could start with a clean slate. Again cut inside the spot welds and made a flap. I cut the pipes first with the cut off wheel and finished with the reciprocating saw with a wide metal blade. Went better than last time but still a PITA.


I also had bought a couple of 2.5" 16 gauge U bends from EBAY. The radius was too wide so I had to cut out a section in the middle of the bend to tighten it up a bit.


So I can attach the inlet pipe to the drivers side output pipe pretty easy. The 2.5" pipe just slips into the input pipe so makes for a pretty good fit. I'll only be able to weld around half of it (unless I cut open the other side of the muffler) so I'll still get a bit of blow by. I cant really weld the U pipe to the output pipe as there is some type of packing between the two layer of steel. So again a little blow by will happen. I will attach some type of strap there to reinforce it a bit.


So the question is how loud would this set up be?? There is still the perforated input pipe (see previous post above for pic) which will still quiet things down, a little blow by on the U pipe,,, plus the perforated pipe and packing in the output pipe.


Originally I wanted to route the input pipe to both output pipes. The issue is the passenger side pipe is on a slightly different plane than the other two pipes (see second pic). I think I could cut a bit of a Y pipe off of it and get the exhaust routed there,,, but it'll be a chore,,,, and maybe make it too quiet. We'll see.....
