    Rebel GT Exhaust question

    My 2023 Laramie Sport came with G/T resonators so I needed the muffler and drivers side resonator assembly part # 68517364AA. The G/T Left Resonator has this number stamped on it C-9408-L the right C-9408-R the G/T muffler is stamped C-9396.

    Rebel GT Exhaust question

    The cabin sounds fine it's not obnoxious at all. Yes it sounds throatier than the standard DT Hemi and worth it. The muffler and drivers side resonator are connected as 1 long piece. The passenger side resonator is on a separate pipe that slips into the Y after the muffler.

    Possible Hurricane misfire at cruising speed.

    I get it there is obviously some mechanical/software issue going on there. I hope it gets fixed soon.

    Possible Hurricane misfire at cruising speed.

    I know the manual says 87 is fine probably for better marketing. These engines run best on premium I've seen gains with ignition timing and holding boost longer using 93. Direct Connection states Fuel Type: Premium and it's the same Standard Output CAT1 Hurricane engine in the RAM.

    How often do you change your engine oil?

    My 1sth oil change was at 1K then every 5K or 6 months after that. The 3.0L it's much easier to change than the 5.7L. Interesting that GM's recall fix for the 6.2L is to go from 0W-20 to 0W-40 oil or replace the engine depending on the diagnostic code.
