    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.

    Possible Hurricane misfire at cruising speed.

    I'm curious what fuel are you using regular or premium?

    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.

    Hurricane and Coolant Levels

    No they are separate systems the intercooler reservoir is much cooler when the engine is running since it doesn't run through the block.

    Hurricane and Coolant Levels

    I didn't pay attention to it initially but did add coolant to the intercooler reservoir. At the time it was sitting just above the min level and filled to max level. So far it hasn't changed it's level and it's been several weeks since it was filled. The radiator reservoir is at the max level...

    Cold air intake

    I'm sure Mopar will have their own CAI too like they do for other models. No need for a aftermarket BOV since you can hear it having the CAI.

    Cold air intake

    With the K&N CAI it removes the resonator tube that sits on top of the engine and the air filter and air box are no longer a choak point in the induction system. For me there is a gain in turbo/bov sound and increased air flow so it's not a waste. I don't think there was a 41HP gain but it does...

    Cold air intake

    After putting on my K&N CAI you will definitely hear the turbos and bov. I put a Filter Wears pre-filter over the K&N filter to keep out any potential water since my sport hood vents are functional.

    2025 RAM 1500 3.0L SO S&B Cold Air Intake

    Today the K&N CAI got installed the CAI wasn't too difficult. Pay attention to the direction of the MAS sensor it's easy to get 180 degrees off. I compared the Intake Air Temp before and after the installation it tends to be 2 degrees cooler than the stock box. It seems to recover faster from...

    2025 RAM 1500 3.0L SO S&B Cold Air Intake

    Instead of waiting for the S&B to finally be released, today I purchased the K&N online from Beef Cake Racing looking forward to the 41HP gain or at least audible turbo spool. lol

    2025 RAM 1500 3.0L SO S&B Cold Air Intake

    How does the K&N sound can you hear the turbos ? Is the air duct retained that goes next to the radiator?

    2025 RAM 1500 3.0L SO S&B Cold Air Intake

    I found a vendor by using the S&B part number they mentioned it would be available in March. I guess they were being optimistic.
