ATP 3" catless DP install

I'm doing the install on my ATP downpipe this morning. I'm hoping for good things as the stock exhast is super restrictive. This should be a healthy increase over stock.

I'll post pictures and driving impressions later today.

fyi, the car is a flashed 06 MS6 with MS CAI
 
sounds much deeper than the stock exhaust. I had been driving around with one of the mufflers off and it had a wrx-type sound to it. This sounds good with both mufflers and the DP.
