So I just moved to Denver from Colorado Springs (which doesn't have emission testing) and I was planning on get a catted DP just to pass emissions. It would seem that is a waste of time and money. I'm now wondering if I even want to get a DP. I'm now just thinking about an intake and a tune from a local shop. My question is: Is a intake and a tune even worth it? Will I see any noticeable power gains? I own a 2010 WRX.
