The stock muffler failed on my Ford Ranger. Was looking for an upgrade part. Overall, the JBA product is well made. The welding is top notch. There were quite a few rough edges and burrs from the fabrication process. Being a perfectionist, I de burred the sharp edges with a die grinder and put the parts through my bead blast cabinet. It created a uniform matte finish that looks great and is easy on the hands during install. Have not yet accessed performance.
