Which is better? trying to get some opinions before I order my Downpipe soon. Originally I was going to order a Catted Cobb Downpipe for my WRX but now I'm kind of in between because The catless Downpipe is cheaper and I can order more aftermarket parts for my car at the same time. I know it's a noob question but I've heard that 03 wrx's don't have a problem with boost creep. Is that true?
