I'm curious to get my car back today with the smaller muffler. We changed some piping diameters, tip style, and muffler size to hopefully reduce the bassier frequencies and bring out the higher ones. Also hopefully this resolves my 3500rpm rasp issue - really hope it was the single walled 4 inch tip that was the problem.

Hopefully this brings out more 2JZ/RB at high revs, but I won't complain if it's just a louder version of what it is now - a twin turbo M3 sounding naturally aspirated is an achievement in itself haha.
