Product was purchased to provide maximum flow for my '95 Chevy C1500, 4.3L V6. Before my purchase I contacted Flowmaster before purchasing for their recommended muffler and the 70 Series was recommended because I also wanted the quietest muffler possible. I had a whole new exhaust system installed including a new Flowmaster Universal Cat and the muffler was placed just ahead of the rear axle as recommended. While it met my expectations for increased flow, the drone in the cab was a surprise.

great product
