MDS....Did you turn it off or leave it on?

[Graygoose]

I can never tell when it's active. Mine is a 2019 1500.

stock exhaust? Stock exhaust its way less noticeable. It never bothered me before neither.
Until I could really hear my exhaust.

Never bothered me until I added the Magnaflow catback, then the MDS is annoying. Thinking of a Pulsar so no more MDS. For now, manually shifting down to 8th gear.

Interesting. I added the 22" MF muffler only..welded in. Drone annoys me a bit. MDS not

Still have resonators @buddy guy ?

I turn it off every time I get in the truck and I notice it right away if I forget to. I don't notice it just because of the exhaust note, it just makes my truck feel really sluggish.

Wish it didn't have it at all.

What gdawg said!!
2nd nature as soon as its out of park I start poking the gear selector buttons!
Mufflex magnaflow D18 makes MDS sound like a import with a fart can exhaust..lol as well as feels like it's struggling/sluggish

I turned it off with a tune. The sound was horrible with the shorties and the SLP Loudmouth... and as some people already said : I paid for a V8 and I want my 8 cylinders to do their job all the time. If I had cared about mpg I would have bought another car.

For me it was this as well. It never really bothered me until i switched to a Borla muffler. I couldnt stand the exhaust note when it was on... sounded like a loud import car exhaust note...so I went into the tune and turned it off.

this is a copy of a post i put up not too long ago on how i feel about MDS

"speaking just specifically from a "design" point of view, the MDS is a very intelligent concept.
However, from a purist or connoisseur's perspective, it's a complete and utter sacrilege to the HEMI's character. i myself absolutely LOATHE the MDS. I'll even bet the SRT engineers silently wept among themselves while putting those abominations (collapsible lifters) into a motor with such a revered heritage.
i have a pulsar and i still run my truck in "8" on the steering wheel. i have been doing it so long its natural. i paid for a V8- i demand all 8."

I turn mine off as well, sounds like a fedex truck with it on, lol. On a side note, I can now use cruise with the MDS off. Couldn't do that before I had the cruise control recall done.

I leave mine on (for now). I struggled to tell it was even on with stock exhaust.

With my Borla ProXS on, I can tell when it kicks in, but it does not annoy me at all.

I've seen some claims that it actually has been giving some guys worse MPG, so I am considering trying to do a test to see how my MPG compares between MDS on/off. I like to play in my truck, but doesn't hurt to try to get the best MPG I can while playing being it is my DD

I've seen videos about the mds and although you can save fuel but with it off you can save your engine.
I purchased the pulsar on my 2017 ram and with the 4 performance modes you have the option on or off ...I totally recommend the pulsar.

Yes Ive read a ton, I really wanna get rid of the MDS, and 25-30HP would be nice.

 

[88ROOK]

i had the pulsar, while the HP is noticable doesnt compare to a custom tune. sold my pulsar and went the custom route. also went from 12.5 mpg to 15.2 with mds off. the biggest perfomance gain to me was in the tranny.

Thanks all, I finally realized I can turn the MDS off without a tuner. Late to the game but great info.

When I bought the truck I stopped caring about MPG.

One of the benefits of being American- MPG doesn’t matter!

I had a hand held tuner for my charger and liked it also but I like the convenience of on the fly changing which by the way is updatable for custom tunes aswell I just have to get the cable when tunes are available.
Had them both and both work well!

I've been debating the pulsar. Initially it was hard to find many things about it, or everyone was saying hold out for a custom tune...

I've had canned tunes on my last 2 vehicles and could tell a huge difference on them..

You guys might just convince me yet to get a pulsar .. just need to convince the wife it's needed then

what do you need to change on the fly?, i have the PC also which is nice cause the wife doesnt like to do burnouts at every stoplight cause shes not use to touchy pedal, so i can adjust that down to city mode for her........ the kids say mommy drives crazy and does burnouts
