I didn't go to the dealership for this reason haha.
I wasn't confused until he started talking all this crap. I already know that the s-tune nismo is a catback, but I noticed at the dealership that the Nismo Z only had one muffler..which makes it non-dual..right? I'm so lost but I don't care that much..just curious. They made it seem like my exhaust is better...
