280zzzz Posted August 18, 2009 Share Posted August 18, 2009 Our plan for exhaust is 3-2 headers, into dual pipes down to where the spare tire well used to be, into a home built muffler that is two entries, with a y pipe inside, making four outlets. The inside pipes will be drilled and there will be some kind of filler inside the muffler outside the pipes. The 4 exit exhaust pipes, will then dip down and exit out a cutout in the bottom of the rear valance. Anyone have any ways to up this design at all? Ill be sure to post pics and a write-up in a few weeks. Quote Link to comment Share on other sites More sharing options...
