- Although, I think warpspeed did some dyno tests once.... Mikey P (93 SE) 06:58:08 6/19/2002 (4)
  - they tested it on an S/C'd 4th gen. SC and turbo are COMPLETELY different principles and testing on the other type of system can't be used to reliably size exhaust. nm Matt (93SE) 10:47:19 6/19/2002 (1)
    - Oh, I didn't realize that it was a SC not a turbo. makes sense. n/m Mikey P (93 SE) 11:23:30 6/19/2002 (0)
  - When spinning a big TO4, 3" should be your minimum, or so I've been told. Lemme check with my exhaust guy who did my last exhaust. n/m The Max (92 J30 Maxima (turbo project underway)) 10:20:08 6/19/2002 (0)
  - Sounds good, I'll give them a call. Thanks n/m MIKE (93VE) 09:10:31 6/19/2002 (0)
