I think I got a little ahead of myself here.. Backing up.
I finished up the 4" Y-pipe. What a PAIN it is to cut such large pipe on an old worn out chop saw! I had a LOT of gaps to weld up and it took a minute to get the Millermatic 212 back to where I like it to be. It turned out alright. The picture to follow was before I hacked the perforated metal and fiberglass mat behind it out. Probably should've left it in for noise purposes but eh, she loud.
This is the best picture of the exhaust I have taken. Odd as it has been on for quite some time now and this picture was taken Saturday evening.
