From the open Y-pipe on my 2000 transmission to this one with a 4 inch bend right in front of the axle. This exhaust setup sounds heavenly. It's not as loud as they say. In my opinion, this is ideal for a weekend strip machine in particular. It gave that ugly open pipe sound a much needed tone and helped deaden it a lot more than I thought. I should have done this a long time ago. The muffler is of excellent quality, as are the welds.
