Corvette Z06 muffler mod

 


Per our customers request we went into the mufflers and capped the perforated larger tubes to basically create a straight pipe and we perforated the smaller tubes to quiet the exhaust even more with the valves closed. The pictures below from left to right are from start to finish. The passenger muffler would not come out of the car without removing a significant amount of the car. So we dropped it down and did the mod under the car. Total time invested was 5 hours. The customer reported a louder, but pleasant tone with the valves open and a small reduction in drone with the valves closed.
