Bolt On Filter Back Exhausts

The stock exhaust on the 6.4L Super Duty is heavily restricted by tight, crushed-bent factory plumbing, creating backpressure that chokes your sequential compound turbos and drives EGTs up under load. Upgrading to a mandrel-bent aftermarket exhaust clears that bottleneck — lowering thermal stress on your cylinder heads, helping your turbos spool faster, and uncovering that deep, common-rail diesel sound.

Shop DPF-back exhaust systems in 4-inch and 5-inch configurations from MBRP and AFE Power, available in aluminized steel or T409 stainless steel depending on your climate and budget. Choose single or dual exit, in polished, black, or SLM finishes, correctly matched to your cab and bed configuration. Whether you're chasing lower towing EGTs on a daily driver or a more aggressive exhaust note, we carry the direct-fit system to match.
