Ok I'm going to be dropping in an LS motor into my 93 Civic VX hatchback within a couple of months, and I know I'm going to need an aftermarket exhaust. The only problem is that later down the road say within the next year, it's going to be turbocharged. The thing I'm wondering is, am I gonna have to get a different exhaust when I turbocharge it? I know most N/A exhaust are 2 1/4" piping, and aren't turbo exhausts like 2.5-3"? I don't wanna get the turbo exhaust right away if it's gonna make me lose back pressure on the LS motor. What should I do? Is 2.5 big enough for turbo, and small enough not lose backpressure on the stock LS motor? Somebody help me.
