    Really? My CM All4 has always been fine with 50mph in 6th, even before I changed my exhaust.

    mine was not:
    1) fuel consumption was higher in 6th than in 5th at 55 mph
    2) the engine bogged at 55 mph in 6th if the gas pedal was floored
    3) the engine ran rough at 55 mph in 6th

    all of the above indicated to me the engine was at to low RPM in 6th gear at 55 mph

    none of those apply after the exhaust upgrade

    I installed an Magnaflow on my CM All4S a couple of weeks ago and love it. You are correct on the deeper tone. I had Magnaflow on my R53 and it was way louder but then again, the exhaust on most turbo cars are quieter.
