After being confused plenty of times since posting my stock exhaust, and dp, through pms I had many questions asked about axle back, cat back, mid pipe, down pipe. I thought this would help some people, as it did me. Matt also helped too, thank you. forgot to add my source before I gets introuble clubwrx.net.
where does the BOV/BPV send back it's air? I know it's after the MAF but is it before or after the turbo, guessing before...
