I have currently bought a 2011 WRX and the guy who had it before me put in a cold air intake but did not get a tune or a downpipe, I am trying to learn about all this stuff for the first time, but it seems like I am getting hung up and what I am sure are very stupid things. So I have heard getting a DP and a stage 2 tune would be the best course of action, but looking at DP's online has proven to be very frustrating for me, so could some one please explain a few questions I have
What is the difference between catted and Cattless? The things I am concerned about is noise and what's best for the car, not so much power, I like the sound of the exhaust as is and don't want my car sounding like a car from Tokyo Drift.
What is the difference In between Cobb bellmouth and CNT bellmouth? Or divorce waste gate for that matter, or even invidia. Cobb is $595 and I found a CNT that looks to be the same and have the same features but for $350. Am I just paying for the name? It just seems like the price for a DP Fluctuates*so much but I can't really seem to find out why.
I am sorry for the stupid question but I did not know who else to ask, thank you in advance for any responses.
