does anybody have this system in there evo yet??? and if you do, how is it working for you, did you feel any throttle response and how much horsepower did it give you???

 

Try a search there was just a post on it. Nothing major, but sound is much better.

 

I just bought an adapter and an AEM filter. You can definitely hear the turbo spool up and the stock BOV dump air even when inside the car. It is a very cheap (around $50), easy, and really sounds awesome. As far as performance, they MIGHT be a few HP and definitely better spool up time, and saves you a few pounds. You dont have to get an RMR. Anything that will fit an Eclipse GS-T will do, but you cant get a big filter because there might not be enough room.

DO IT!!!
