I was thinking of replacing the stock downpipe and replacing it with a aftermarket.

From what i have read, the ebay specials are not that great.

what I am thinking is keepint the stock and not worring about it cracking or having to remove the sensors to put them in a new downpipe.

Really, how much power will I gain?

assuming you are doing a 3sgte swap with the stock turbo, then there a few downpipe options that are "off the shelf" ready. The most cost effective is probably Berk. The other very good 3" option is Aussie. Also, KO racing makes a 2.5" one that I would probably buy (because I am over 30 and the 3" is noticably louder). Make sure you get it ceramic coated if you don't get stainless.

Also, I think 20 hp is a bit optimistic. I would say more like 7-8hp with a 2.5" and 8-10hp with a 3" at 15psi.

i know your trying to do the right thing for your motor, but this is one of those times where you should just trust the guys who have had their swaps for a while and have done a ton of research into this.
