Brad-ManQ45 Posted January 10, 2006 Share Posted January 10, 2006 The 280 ZXT's had 2 3/8" exhaust pipes, so you are bigger than that now. For an NA engine, I imagine 2 1/4" pipe would be about right. Quote Link to comment Share on other sites More sharing options...

Drftn280zxt Posted January 19, 2006 Share Posted January 19, 2006 2.25" sounds right to me. I think I remember the exhuast telling me that 2.25" was the diameter of pipe before making 3" exhuast, but that was in my old LOL 79 280zx 2+2 Quote Link to comment Share on other sites More sharing options...
