Upgrading our stock exhaust to a 4″ MBRP exhaust system for my 7.3L Powerstroke diesel.
The Ford F250 Superduty with the 7.3L Powerstroke diesel engine is great from the factory. However, the intake and exhaust system leave something to be desired when it comes to efficiency. The small exhaust system that comes with the truck is very restrictive and can be detrimental to turbo efficiency when towing or daily driving. When the turbo cannot push air through the exhaust effectively, the truck suffers. In comes the MBRP 4″ exhaust system. This exhaust system is nearly twice the diameter as the OEM exhaust system on the 7.3L Powerstroke diesel engine. The installation is not terribly difficult and the improvements are immediately noticeable. When towing, my truck feels like it can breath and push air very effectively through the turbo and exhaust system. This improves MPG and drive-ability and the truck does not have to downshift when climbing small hills. Check out the video that includes the entire installation process and first drive!
