I purchased the “GTS” exhaust system from Wilkerson 5 or so years back. The headers are fine but the Cans had a heavy drone around 2500 rpm. After a few months the spot welds started to break loose and along with the drone it sounded like a handful of nuts and bolts were rattling around inside. The very thin gauge metal made welding very difficult. I ended cutting the cans off and replacing them with the dual big bore mufflers PIM used to sell. No drone and nice tone. A tad loud but only when I jump on it. I like how they look too.
