Dynomax Ultra Flo SS Cat-Back Exhaust

Dynomax Ultra Flo SS Single System 39315 is a premium cat-back exhaust kit built for the 1998-2011 Ford Ranger. It combines stainless steel construction with a polished muffler and mandrel-bent piping to deliver a direct-fit performance exhaust upgrade for Ranger owners seeking improved exhaust flow and a cleaner rear exit.

Product Details

Dynomax Ultra Flo SS Single System 39315 is built around a straight-through muffler design that Dynomax rates for high-flow performance and reduced restriction. The stainless steel muffler construction and polished finish support long-term durability while giving the rear of the vehicle a cleaner appearance. Continuous Roving Fiberglass (CRF) technology is used to control unwanted cabin resonance while maintaining a deeper exhaust note.

This system is a strong match for drivers searching for a Ford Ranger cat-back exhaust, a 2.5-inch stainless steel Ranger exhaust system, or a polished performance exhaust for 1998-2011 Ford Ranger models. The kit contents include the flanged intermediate pipe, muffler, tail pipe, clamps, gasket, and hanger needed for the exhaust assembly.

Common Uses

• Replacing a restrictive factory exhaust on a Ford Ranger
• Restoring exhaust flow after corrosion or damage
• Upgrading to a polished stainless steel cat-back system
• Reducing interior exhaust resonance while keeping a performance tone
• Improving rear-exit exhaust appearance with a 3-inch stainless tip

Installation Notes

This Dynomax exhaust system is designed for bolt-on installation on listed Ford Ranger applications. Verify model year and exhaust routing before installation, and confirm clearance around the tail pipe, hanger locations, and rear exit angle. Because this is a cat-back system, it installs behind the catalytic converter and does not include an oxygen sensor bung.
