Dyno Day RENNtech AMG GT R Before and After Cat Downpipes Swap

We’re making more horsepower today! Dyno-Comp in Scottsdale, AZ installed my RENNtech downpipes and high flow cats on my RENNtech Mercedes AMG GT R, and I’m really impressed. Before the exhaust was installed, we did a baseline dyno run where the car made 611 wheel horsepower and 639 lb-ft of torque on Arizona 91 pump gas. After the exhaust was installed, we did another dyno run and the car made about 20 more wheel horsepower and 25 more ft-lb of torque without even tuning for the new downpipes!

I’m pumped about the power increase and can’t wait to get out and drive the AMG some more. Make sure you’re subscribed so you don’t miss any content featuring this RENNtech AMG GT R and my race car Porsche GT2 RS Clubsport!
