Muffler delete shouldn’t affect the engine at all. Air fuel mixture is based off the O2 sensor’s lecture of the exhaust gas before the catalytic converter. If the air fuel mixture is not correct, the PCM will change fuel delivery to achieve a perfect ratio. A four stoke engine has to have 0 restriction to it’s exhaust to perform any power. Therefore removing the muffler by a straight pipe shouldn’t change the flow of the exhaust. However changing the size of the exhaust pipe will have an impact on how fast the exhaust gas flow. Variable valve timing and adaptive fuel trim will correct any change in the engine performance, so even then no gain or loss in power should be observed. I would say that a feeling of power loss after a muffler delete is more a placebo effect than anything else.

I mean potentially. I don't have dyno numbers and merely made this video to see why people were complaining about power loss and realistically the amount of potential power loss is going to be minimal. The reason I would disagree with you however is because no matter how well the PCM can manage the fuel. It can't add air or oxygen into the cylinder on a N\A engine. So if the cylinder scavenging is affected in a negative way and can't suck as much fresh air or oxygen into the cylinder you are going to end up with less power. of course the PCM is going to manage to fuel accordingly but if there is less oxygen to burn you can't add as much fuel to keep to that stoichiometric ratio. the Scavenging effect on a N/A engine is well documented to increase torque and horsepower. So I think the question is how much does a muffler delete really effect the scavenging on the 5.7 Hemi and I don't know the answer. but still an interesting topic. The VVT is interesting though, That could potentially effect the total valve over lap if needed. I don't know if that would correct for scavenging issues. Let me know that you think I'm curious now.

very interesting! Like I mentioned in the video I really didnt notice any difference in power either way. that being said I wasnt looking for any differences either! I'm hoping to slap my muffler delete pipe back on here in the near future and see if I notice anything this second time!

I did this to my new 2013 Ram 5.7L and it sounded awesome! I miss that truck. I did the same thing, cut the muffler out, add a y-pipe, and extend the pipes. Left the cats and the rear resonators and stock tips. The drone didn't bother me. I would always put my truck in 6th manual or tow/haul so it didn't run in 4-cyl mode. My truck ran 14.6@96mph in the 1/4 mile.

Definitely will be binging more of ur stuff definitely know what ur talking about it! If ur ever in the Tsawassan area would love to chat rams with u I’m on my 3rd and absolutely love them would love to pick ur brain and get to know another ram lover!

Good information, makes sense, glad I watch this video, I can also relate to the information because of a similar experience with a past modified exhaust , I experienced a very annoying drone sound at certain cruising speeds and as well as a noticeable loss of torque but the sound was nice. Yeah I think I will just not touch the exhaust on my 21 ram 5.7 lol.

Thanks for the info!!

I got a 2012 ram 5.7 with stock single exhaust. Well the other day I noticed a change in the sound. I got underneath and noticed the pipe had completely separated from the exit of the muffler. I removed the dangling pipe so now my truck has no visible pipe. It sounds good. If I were to just cut the muffler off would it be loud af.

Great video and great honest info as always Alex!... Not sure why you don't have more subs...? bet most guys don't think twice about the engineering component to changing exhaust...it's all about that V8 sound LOL, and I get it.

Have you done a video on washing the motor ? Enjoy watching your videos.

If you were to install the exhaust wrap around the muffler, delete piece and back from there, would that help the drone noise in the cab? Or would I have to use some spray insulation along the floor boards underneath such as the gravel guard spray or something along those lines? Would that help insulate some of the drone noise entering the cab?

Some exhaust will cause you to lose low end torque ! I bought a magnaflow muffler delete and left my resonates on. Sounds awesome with very little drone !

happy you have little drone. For some reason for me around 110km/h i would get this unbearable drone. but other then that the truck was pretty quiet if I wasn't mashing the throttle.

I have a question. Does gutting a clogged cat causes burnt valves or no? I had to gutt the main cat cause it was clogged on my truck and at 206k it cut down to 4cyls instead of 5 on a 3.7L

Would it really cause that much of a loss in scavenging with the stock manifold and cats in place?

I have that same exact truck that you're standing in front of I did the same thing in 2014 when I bought the truck and had no problems same power the only thing I had to do to this pick up is put a water pump on it still pulls strong and runs good

From my experience in motorcycles the torque curve can be effected greatly by the type of exhaust. Packing, length, diameter. Straight pipes always lose torque over a muffler unless your engine is specifically built for a special application. (Racing) that being said those engines would gain torque with a muffler but they want high rpm hp and would lose that. There’s also the argument of heat. Straight pipes lower head temp and egt. Turbos are a different can of worms all together. Without typing 10000 words I’m just saying most people don’t tune their engines properly for the intake and exhaust they have.

Your information would be true if the 5.7 didn’t have variable valve timing, vvt negates any power loss at low rpm because it doesn’t let the valves open as far. So no deleting the muffler does absolutely nothing to the tune.

@@kogoat2390 then your car doesn’t have VVT or it has some other system that is doing that. The muffler is after the O2 sensors. Changing cars or changing exhaust size changes how the vehicle runs. Changing the muffler or a resonator does nothing we wot add sound and or drone. The stock muffler on these trucks are very good and flow great.. so not much change to airflow or scavenging therefore. O change to fuel mileage, power or anything else.

I’m running and recommend the Borla Pro XS muffler. Not super loud. But amazing sound. And turn your stinking MDS off. That’s where all your drones coming from. It’s going into V4 mode. To do that you put it in drive. Hit the gear - button on the steering wheel. Then hit the + button all the way up to 8. It’ll shift like normal, but will stay out of MDS mode. It’s a stupid system. I noticed no mpg gain with it on. So I do this every tine I drive. May eventually get a tuner and permanently turn it off. But I’m cheap 😂

trust me the drone was not from the MDS lol what was kind of cool though (because again it is such a loud set up) is when the MDS kicks in, the truck has that very distinct Subaru 4 cylinder rubble. and its clear as day when you get on the throttle the pitch totally changes to much more V8 rumble a much higher tone. I thought it was kind of cool. but on the highway at like 120km/h the MDS system is for the most part shut off because of the slight increase in torque demand to remain at those speeds. That's my experience at least lol no idea if there is truth behind it I haven't dug into the in's and out's of the MDS system. its interesting how to didn't notice fuel economy differences. the biggest differences. how do you normally drive ? like just around town or manly highway?
