The SuperSprint Performance muffler has added yet one more benefit I had not expected, INCREASED FUEL MILEAGE. My first tank yielded an average 20% city/80% highway @ 80MPH of 18.1 MPG, which is up from 17.4. Muffler has a slightly deeper tone with the first 300 miles. Ecstatic with this MOD !

Just wanted to report that I led a convoy down to Washington DC and cruised at 70 all the way, my MPG went to 22.8, best I have ever had and the slowest I have ever driven :-)
