I would like to install a o/r hpipe but I live in ny and I have to worry about inspection through the obd2 port. I'm not worried about the visual part. My question is that is it possible to install the o/r pipe without getting a tune. I want the pipe for sound and I would like to remain stock otherwise. I would install the below anti-foulers and I am hoping that would be good enough. http://www.teamjdm.com/02-exhaust-bung-extensions-non-foulers-for-off-road-use/
