Dump pipe expands to 4" off he back of the turbo and stays 4" to the back of the car. There is a 5" body metalcat just under the seat that is fitted with 4" v-bands for easy removal. Only muffler is an 8" x 5" box on the back.
The setup isn't quite finished in some of the pictures and some of the others are a little fuzzy because of bad light and phone camera.
Finally have this setup running in the car... two engine builds later it's making 550whp @ 26psi
