I had my exhaust shop install a 3" mandrel bent system from turbo back today using a Hi Flow CAT and a single free flow Muffler. He also installed my EGT sender in a more suitable position. The whole thing only cost me $540 too, but i did have the CAT in my garage lying around (from my Turbo BMW, only had it on for modification plate approval). Was told a cat would have cost around $280.
The acceleration is much better now and definatly come on boost stronger. Will wait for the DP Chip on Friday before i up the boost some more (at 17 psi now) to 20psi. Here are some very quick pictures i just took.
