By now I'm sure most of you know that I have a '90 Laser RS Turbo. Since it is a turbo car, I was wondering what the appropriate size of exhaust would be. I don't have any mods done to the engine or turbo. I'm starting with exhaust.
I was thinking somewhere around 2.25" for now. Maybe 2.5". I've always heard that its best for turbo cars to have bigger exhaust. But mine isn't modded, and its also bad for cars not to have enough backpressure.
