This week at CR Performance Engineering Inc. we have just completed our first off of the ST2 50mm/68mm (73mm Ex Tip) upgrade for 2018-2020 3.0L F150 Power Stroke Diesel. We will also offer ST1 & ST3 options to customize performance to your needs.
The ST2 is a excellent upgrade from the 41mm stock setup for track and street performance, or towing performance applications.
