3" muffler tip???

i'm thinking bout buying a new exhaust, the one i have now is a HKS hi powered, 2.5" tip, for a stock 96 240. will it be any diff if i buy a 3"??? will i gain or lose power??? and what bout the piping is 2.5" pipe good or 3" better??? thanks.

the 3" will be louder, you will loose a couple horsepower at low RPM's.... but you will gain about 10 rwhp towards redline over stock... more of a gain then a small diameter aftermarket catback on a naturally aspirated KA.

just tip wont matter at all.
but if your talking about the whole exhaust then SR20DET summed it up

Using larger piping will free up some HP like SR said. I'd go for the larger piping personally

getting a tip is like stuffing your pants with socks, its all looks and doesnt do shit in the end
