You should go at least 2.25 for an SR20 or you’ll really be choking it off. Pace Setter will rust out within 1 or 2 Buffalo winters. But pretty much anything costing you less than 300 bucks will probably do that.

Yeah, 2.25-2.5 would be good. I got a 2.5 Stillen catback on my 91 SE-R, but I couldn’t find it anywhere on their website, so it’s probably been discontinued.
