GReddy wasn't mating up to the Aussie pipe do to the fact that Aussie makes one pipe that is supposed to fit the mr2 and celica. I think the fitment is not perfect because of this. The GReddy was about 1/2" to 3/4" off it's mark. So I commissioned my buddy Steve to weld a flex section into the b-pipe. He went a step further and made a beautiful section betwen the downpipe and the last bend on the b-pipe. I give him props because it turned out perfect and he came through in a pinch!

My previous setup was the Hux 2.5" downpipe and SARD Turbo exhaust which starts. I made 277whp and 312 ft/lbs tq on it. I could not hold 20psi to redline, it basically tapered back down to 15-16psi. Which you can see in my dyno graph. I figured I had too much back pressure. I first installed the Aussie, and already noticed better results. At the same settings on the boost controller I was making about 2-3psi more. Also at high boost (18psi) it held it all the way to redline. I haven't done any more testing past this yet. I will be hopping back on the dyno as soon as I can get some new rear tires to give you guys the results. Here is a pic of the custom pipe.
