Shorty headys from pacesetter, dual 2.5 from the front of the trans going to 1 magnaflow muffler with turndowns (tailpipes coming soon), I removed the mesh from in front of the stock MAF sensor, EGR block off plate, jet stage 2 piggyback chip (complete waste of money(, and a 180 thermostat. I'm hoping to take about a half second of my 1/4 mile. I have a accel coil that I havnt put on yet and I havent grinded the lip off the throttle body blade either yet. It probably wouldnt be hard to talk me into a small shot of nitrous too.

here is a good read to start with if your curious about the marine intake:
