I have read a bunch of posts about people having bog issues when adding a CAI or SRI. This was my first thought when thinking about making the engine louder, but I don't think I was to add an aftermarket intake now because of bog issues. What are my other options? An exhaust would be nice but I don't have 600-700 for a nice exhaust system. Would the 08 WRX exhaust make a difference? I don't want to mess with the CAT... I did that with my RSX and got nothing but trouble.
