Service Engine Light Soon Light after Exhaust Install

That is a code for a evap leak. Usually it's just the customer forgetting to tighten down their gas cap after a fill up or whatever but in this case your evap canister might have a leak. Check for loose hoses or cracks at the evap canister.

I got that exact code after installing my short tails. It was about a day or two after and I pulled the code, which was identical to yours. It's an EVAP code, specific to Nissan and a few other manu's. I reset it and never saw it again.

After this I made it a habit to click the gas cap five times instead of two...

I would say you nicked the cannister and it is leaking slightly when you get pressure up after a fill up or on a hot day. Check see if new pipe is rubbing the cannister now in the area you shaved. Maybe put a daub of caulk on the spot you shaved and see if that seals it. Even better is some liquid electrical tape rubber you can paint on with a little brush provided on the can.
