So, I looked under the back end to see the exhaust, and it's a single pipe to a muffler with 2 exits. At least from the muffler, it's 2 in diameter. I need to measure further forward to see if it's 2 in diameter all the way to the cats.

For the JBD or any of the tunes, will the dealership be able to detect it at all? Like, they cannot detect that we threw codes or reset anything?

Does anyone know if our IC is in the front grill or on the left side? If it's in the front, what's the cooler on the left side? I asked in another thread if anyone has a tech manual before I start modding.
