Just got my STi last tues!!!!!!!!!!!!!!!!!!1

Want to do some basic mods like and intake and some exhaust.
What is working for you guys, the last think I want is CEL. I am willing to look at just muffler all the way to turbo back.
What do you guys think about the blow-off valves and oil catch cans available?

Any input is valued
Thanks

Out of what you mentioned I would do the oil catch can. The intake is not worth it until you get some engine management. A turbo back might produce some boost creep without some other additions. A blow-off valve does not do anything except make noise and if that is what you want you can remove the resonator from the stock intake and be able to hear the turbo and the stock bypass valve clearly. Good luck and congrats.
