i'm looking to buy a new downpipe for the evo i have a extreme boost open dump right now but looking to make it a little queiter but i dont wana lose the power that it put out right now i am looking at AMS, ETS, and ATP tell me what you guys think would be the best.....

 

If you want quieter you're going to have get rid of that open dump. I would recommend AMS. It's the only cast unit on the market, and the opening on the turbo side is huge. You can literally fit your entire hand and some of your forearm in there. Now if you're looking to get a brand specific turbo kit down the road like ETS or AFI don't waste your money.
