Found a pic of a stock exhaust for a 2017
552660
The stock exhaust on my 2017, however, looks like this
552661
Was there an option for a different exhaust from the factory?

That's weird, MDS isnt a player, I would have though it would be the other way around, bullet style for the stick and muffler for the auto.

I think top is 392 exhaust, bottom is 6.2 exhaust, that’s what I gather as I am searching for a stock exhaust as well

Strange. My M6 midpipe looks like the bottom. Has the part number: 05147024AA stamped on it, which the google machine tells me is an A8 part.

Top is a six speed car
Agree.

The Hellcat M6 got the quiet oval mufflers and the A8 got the louder bottle mufflers, backwards from what you would think and what Dodge had done in the past with the R/T.

The SRT 392 and Scat Pack 392 use the top oval muffler system as well regardless of transmission.

It doesn't make any sense to me, MDS used to be the difference when I first bought my old R/T. Anyway I would guess by just doing the Blastin Bob's resonator delete ($130) the bottle muffler system will sound nice. I've seen a couple vids on youtube, but thought some sounded good and other didn't sound much different, this might be the reason....

My wife has an 18 Scat Pack Charger and it had the bottom exhaust. We cut the mid mufflers out for Race Bullets.

My 15 hc a8 has the bullets #2 pic, as do all A8 models I have seen.

That may be why I’ve noticed my Challenger is a helluva lot louder than my Charger. I could hear the SC whine real easy inside the Charger. In the Challenger the SC whine is very faint because the exhaust is so loud.

I was just about to ask the same question. I have the big mid mufflers on my A8 sold new in Sweden. Can it be that they adapt them for different markets? I picked this car up by the dealer but they have touched it. The welds doesn’t look factory made, it says Dynomax on the mufflers?
Anyone know?

Wow, dynomax mufflers on a showroom floor new vehicle? Interesting.

Id bet $$$ those are not stock and were welded in by someone, but WHY. Maybe they OEM mufflers were somehow damaged in transit? Maybe those are to meet noise restrictions?
