Product Details

Dynomax Ultra Flo Welded Universal part number 17234 is a performance exhaust muffler engineered around unrestricted flow and sound control. The oval stainless steel body measures 20 inches long with a 25-inch overall length, and the absorption-style core is built to move exhaust efficiently while the CRF packing helps manage resonance.

It is a direct fit style option for 2004-2008 Ford F-150 dual exhaust applications and 2006-2009 Mitsubishi Raider dual exhaust applications with rear exit routing on either side of the license plate.
