If you are going to stay around stage 1 numbers (235 hp) then the 2.25" exhaust system is fine. If you are going to go beyond that then you'll need a 2.5" system, preferably a turboback system. A mufferless system isn't for everybody. For some it is too loud or after awhile becomes too loud. You don't need a lot of noise to be fast, just as long as the muffler is flow through. With an aftermarket turboback mufferless system on my neon srt-4, after two years, I got tired of alerting everybody 3-4 blocks away that I was coming. I installed a Camaro style Magnaflow flow through muffler and now I'm stealthy quiet, still fast as hell and leave V8's in my rear view mirror. Know what you want now so you don't end up doing it twice. IMHO loud is nice, but stealthy is better.
