Instead of starting new thread I will just post on here, hope the OP doesn't mind.
First on all I'm not a big fan of Sinister, and have ordered their limited edition powermax to get a look at it. It was not a ball bearing turbo that they claimed, and have also tried their other products in the past with disappointing results.
With that said I installed their y-pipe and it was a nice piece on equipment, welds very nice, the way the pipes go into collector also nice. The collector opening is smaller then the orginal size of opening which matches the turbo perfectly. I didn't modify the y-pipe at all just installed and tried it. Well here's my impression of the way it work, very nice, sounded better at idle and there was a noticeable quicker spool, and throttle response. I'm happy with it so far, I would buy one if I was looking to get better performance over the stock pipe for sure. The pipe is all stainless and has a slip pipe expansion joint, very nice piece, will keep updated on the long term but looks promising.
