The fitment of my Stinger cat-back is horrible. The welds are low-quality. The stainless steel is already speckled with tarnish, especially around the stamped Borla lettering on the mufflers. The tips are covered in trash from the poor job welding the hangers. There are even tiny dents in the brand new tips when I uncovered them tonight. And I still can't believe they advertise a 2.5" exhaust system but start it off with a much smaller piece of pipe. It doesn't even seal well with my Bassani X-pipe since the Bassani is a true 2.5" piece. If I could get my money back and have the same sound, I would go with a full Bassani setup in a heartbeat.
