Anyone have the catback exhaust system from Mopar?

[Omac]

Want to know if anyone has the catback system that you can get from the dealer ship. And I was told it is completely under warranty still. If so any clips and thoughts about the system. Wanting to put on my Laramie sport

Mopar Exhaust (77072520AA) Sound Clips

I recently installed the Mopar cat-back system on my Laramie and found that it has not been documented that much. It's fairly new and I could only find a few short videos when researching. Here is a video that has clips of some of the scenarios I was curious about when trying to decide if I...

Will be very minimal! Exhausts do not gain you power, unless you are doing major engine upgrades.

I know it can't be much but also know that a duel exit with a single enter muffler should produce more flow resulting in more power essentially. Of course other things come into the equation with pipe size and initial flow entering the exhaust system which will optimize the amount of power made. I guess what I'm really asking is with how the flowmaster American thunder is manufacturered it should theoretically produce more power. So I guess it just matters what sounds best to you personally. Maybe I answered my own question lol

Well considering mine is going to be pulled and back to stock, sadly that I can not answer for you.

Any reason in particular you’re selling? Not happy with sound? Going another route?

Honestly I LOVE it and this is actually my second one on this truck. I’m selling as I’ve installed a BDS lift and my wife swears it’s now louder. So to keep said peace I am going back to stock.

Sometimes it's better to let in lol I'm just looking for whatever exhaust is manufacturered to produce optimal performance with a stock engine setup. I guess it's still too early to tell.

If you haven't replaced your system yet, check out this thread. MOBORORAM19 added some auger style mufflers to his American Thunder Cat Back to tone it down.

I had this installed a few days ago at the dealer and I couldn't be happier with it.

I was pretty disappointed with the exhaust sound of the DT versus DS models with the 5.7 when I purchased this truck. The Mopar Catback wasn't yet available in Canada when I purchased my truck and I prefer OEM Accessories to aftermarket (most of the time) so I waited it out. Found a pretty reasonable deal for the Catback and the 5" Tips so I decided it was time to pull the trigger.

Here are a couple of observations,

Cold / Warm
It's a lot louder from a cold start than I had anticipated, I've even heard a crackle or a pop once or twice. The noise calms down within 5-10 seconds, after 20-30 seconds it calms down even more. As soon as I figure out how to go about posting videos on here I'll put one up as an example.
You definitely know it's there from a warm start but not nearly as loud as cold.

Cruising Speed
It's pretty quiet but you can definitely hear the difference versus stock, I don't think it would be a deal breaker for someone looking to upgrade but doesn't want their exhaust to be too loud. Absolutely no drone even when MDS kicks in.

Throttle Position
It makes more noise when you push the gas, it's a performance exhaust system that's kind of what it was designed to do. The sound level escalates the further you push the pedal, I haven't pushed it to WOT yet but I've pushed to 3/4 and it sounds magnificent!

Welcome to the Mopar exhaust paired with 5” tips club lol.

 

[Bwsteg]

Are there various mopar exhaust? I’ve seen different part numbers online at versions prices. I have a 2020 Laramie 5.7 with e torque. Can someone provide the part number for my vehicle? Also I assume I reuse my factory exhaust tips? Thanks

 

[PorBoy]

As far as I’m aware after owning (2) maybe three sadly I can’t remember of them, there is only one. Yes you can either use your factory tips or buy their Mopar 5” ones in polished or black...
