You asked about my exhaust. I have a 5" downpipe that runs from the turbo down to about the rear of the transmission where I smoothly transitioned down to 4". It stays 4" back to the bumper where my 4" muffler is. The muffler is a Dynamax Ultra Flow. It's straight through and pretty much just changes the sound a little. I'm either gonna put a 4" Loud Valve dump on the downpipe up front or run a second 4" pipe from the 5" to 4" transition.
