styx0r Posted November 15, 2005 Share Posted November 15, 2005 Ok, here's the deal. I want to have a quiet Legacy for daily driving. I don't want to spend $ on a cat back, because the stock system is very quiet and the stock look is fine w/me. But, I want to have the ability to use 3in pipe w/no restrictions from the turbo - out, on demand. My plan: catless UP -> Turbo -> 3in DP -> 3in midpipe w/ ATP cutout welded in the middle (it comes with a "T" pipe) -> stock axle-back. The ATP cutout is boost actuated. You plug it into a vac/boost line and when boost pressure exceeds the springrate on the actuator, it opens. So - normal restrictive exhaust out of boost, then 7psi+, cutout is open - full 3in. Now, my big question: Can this be tuned for effectively? Remember - any time the car goes out of boost, the cutout closes. While it does open and shut quickly, the movement is not instant. I want one tune that will function properly with the cutout open or closed (and when I say properly, I mean full 3in power levels once the cutout is open + no strain on the stock system when it is not). I would like to spend less than $1500 on a dyno tune + ECUtek or dyno tune + AP. So, can I have my cake and eat it too? Please, discuss. Link to comment Share on other sites More sharing options...
legacy2005 Posted November 15, 2005 Share Posted November 15, 2005 idk if a tuner would be able to tune for the atp cutout since you could go in and out of boost frequently/rapidly. maybe instead of using the atp you could go with a qtp with is switch opperated so you can control when the cutout is open/closed. this would help the tuner out alot to since he could make a map for daily driving and then a different map for when you wanna use the cutout. for a cutout you would wanna run a ecutek since you can have multiple maps for when the cutout is open/closed. Work hard. Play even harder. My Garage Link to comment Share on other sites More sharing options...
