I installed mine a couple weeks ago. Just drove 900 miles to Alabama and it was just fine on the highway. Little bit of rumble to let you know it’s a V8. No complaints from wife, so it’s a winner.
I have the same thing on mine, I believe it is condensation from the exhaust on startup. I have not used the ac on mine yet, but it drips in the same exact spot in my garage.
I went with the J&L like securityguy has and checked it after around 1,200 miles and it was about 2/3rds full. I was a little surprised it had caught that much. I had planned on dumping every 5K miles when I did the oil change, but it will need to be quicker than that.
