Message Well, I could go into lengthy detail about it, but I'll explain it in simple terms and hopefully it'll make sense to you.

There are multiple Japanese Supercars that you'll see run 3 to 3.5" piping. However, any of these cars that are seriously put together and run that kind of pipe will be inline 6s (or even the occasional rotary engine). Why? Mainly because they have SIX cylinders (well, not the rotaty, but you understand) all of which go through ONE pipe. Both turbos and all of those cylinders in one pipe and 3" is usually just fine up to 1000+ horsepower. However, when you realize that our cars have a true dual exhaust system you'll also see that we only have HALF that per side. Only 3 cylinders per side and as such 2.5" piping is fine up to 700-800HP, if not more. By staying with a smaller and still efficient exhaust system, you ensure quick spooling, better response and a quicker exiting of exhaust gases since they don't linger around in such an open space causing turbulence.

Hope this helps...wow, it wasn't so short was it!
