Downpipes
So currently on my 2011 Impreza WRX premium, I have a Cobb sf intake and a cobb catback. Running the ots 1+ sf tune from cobb. Wanted to know what I need to go to stage 2? I’ve read all over some places say you need a cobb turbo back (which I’d have if I went with a cobb catless downpipe, right?) and some say you need a cobb Catted downpipe... what’s the difference besides flow or is that the only difference? I know it’ll be louder but how much louder if I went with catless?

I went stage 2 with a invidia catless turbo back! I didn't actually find it any louder than the catback when driving around normally up to 3k. But when I step on it, it hurts my ears now ***55358;***56611;

You should go to Cobb’s website and it’ll show you what you need to get to stage 2, they even have power packages that come with everything you need for stage 2 and stuff
