I've already done a "before" dyno run and will be doing the "after" run next week. I also have the aFe cat-back exhaust including their Y-pipe.

Just a little note about using a grinding wheel on aluminum. The reason why you NEVER want to cut aluminum this way is not the hardness. Aluminum is soft and "Loads" the wheel with pieces of the metal. This can cause the grinding wheel to become off balance and explode. Same goes for grinding aluminum on any grinder. You need special wheels. I have been in the manufacturing business for over 40 years and cutting aluminum with any standard grinder is forbidden.

Could that have anything to do with the outside temps and even more so the gas stations finally switching back to non winter fuel?
Summer blends were delayed due to this stupid covid bullshit.

Looks like silicon carbide is the better choice. Not sure if those are available for a dremel or not. Fortunately it cut fine for me.

Well, I got the "after" dyno pull done today. I was pleasantly surprised. Jack is a 2019 JLUR 3.6 with AT.

I added the aFe Momentum GT intake with ProGuard 7 filter and the aFe Rebel 2 1/2'" 409 Stainless Cat-Back Exhaust plus the Twisted Steel Stainless Y-pipe.

Before: 48 degrees, 38% humidity, 11/19/2019
After: 70 degrees, 35% humidity, 5/28/2020

Net peak increase of nearly 14 hp. Peak torque is the same, but better at higher RPMs. Nearly identical to stock in both HP and torque until around 4800 RPMs which is also the point where a/f ratio drops. I'm not sure how to interpret that. I'll ask the guys at the dyno shop.

I must be the only one here who is happy with the stock set up. :)

The engine has so much power I have to control my heavy leg all the time and once you get used to the front solid axle then it rides like a Caddy.

Those are the main points people want addressed so I will post the videos below. Also I could care less if you subscribe, wife started the channel. I don't even like being filmed but I enjoy posting jeep related videos to help people.

"Couldn't care less", sorry, it's a pet peeve of mine. Jeep on! :)
