I always love a chance to show my exhaust

A couple weeks ago I changed the muffler from a 3.5x4.5x12 to 3.5x6.25x17 so I have some new pics. Both mufflers are straight through so there shouldn't be much difference in flow and the new one's a little quieter.

The exhaust flange was water cut to match the turbo housing, then the flange ID was taper machined to perfectly match the K27HF2's 2-3/8" outlet to the 2.5 to 3.5 tapered pipe. A short piece of 3.5" elbow is welded to the tapered pipe to point it to passenger side:
