      Comments about Flowmaster Inc. 70 Series Muffler - 2.50 Center In / 2.50 Center Out - Mild Sound:

      I had this installed on my 2000 Jeep Grand Cherokee (287CI) to replace a two chamber welded, non-Flowmaster muffler. The welded non-Flowmaster was horrible, interior drone was just aweful! Further, the welded non-Flowmaster didn't have "enough length" for the exhaust to flow, the guy at the muffler shop said, which in turn robbed me from power, and mileage...Was that ever true!

      The Flowmaster 70 series, 2.5 center in/out, matched up with my Jeep, not only made it sound better, I have a noticeable amount more of low end torque, and average (so far) 1.8mpg (city) more. If I didn't launch from lights as often, I think id get at least 2.2-2.5mpg better than I was. With that said, I can't say a bad thing about this muffler, and will continue to only buy Flowmaster, and tell friends and family to buy Flowmaster as well.
