Looks good so far, too bad you couldnt have gotten a tighter u-bend. Here is a couple pics of mine that I built. 3 inch all the way. I have a few tips listed below.


You dont need much room to clear the oil filter. One thing that I did was belt sand the side of the v-band flange that goes to the down pipe. I sanded it at a slight angle, then sanded the end of the pipe that met it at the same angle so they were slightley oval, this gave it more angle for a sharper bend immediatley off the turbo. But you do not want to "pie cut" the pipe to make sharper bends. This creates "steps" on the inside of the bend. When the exhaust goes over these "steps", it start to tumble or "roll" back over itself. This inturn creates turbulance and slows exhaust flow.

But sanding the flange and pipe makes it a pie cut. That is a little to much thought and insight for the average DSMer who just says "get'er done", as cheap and easy as possible of course. I would guess the slip connection makes a few people ask, will that leak?
