The intake is the fuel / air distribution devise. The plenum, is the portion in the center that all the runners exit from. You have the Exhaust manifold, or in some case's header. that connects to the cylinder head. Then the mid pipe from header to muffler. muffler. tail pipe and resonator. exhaust tip.

 

Don't forget the cats after the manifolds but before the mid pipe. Hellcats also have mid-mufflers. They are before the mufflers.

 

So what’s the difference between a muffler and midpipe and resonator?

 

A muffler does most of the quieting of the exhaust and are typically right before the tail pipes. The resonator helps with the pops and bangs during deceleration. The mid-pipe is what connects the Catalytic converters to the resonators. There is typically an X-pipe or an H-pipe between the cats and the resonators as well. At least on performance cars. Many cars don't have resonators. Challengers (likely Chargers too) also have exhaust valves. When you start the car it is much louder than once it's idle settles down. The valves, when open, allow the exhaust to proceed with no restriction. When they are partly closed, they help build back pressure and quiet the car down some. I left my mufflers on but removed my resonators. The car is louder but does not drone on the highway. Take the mufflers off and expect major drone.

I typically replace all exhausts on my "fun" cars. I'm not doing that with the HC as the exhaust is the perfect blend of mild-to-wild for me.

 

I wish we had a disagree button. lol The exhaust flow pass's through the muffler first and then proceeds down the tail pipe to the resonator. The resonator is the last thing in the pipe...

 

I wish we had a disagree button. lol

You're 100% correct. We need a "wrong" emoji too

On the Challenger HC the mufflers are right before the tails. Trust me, I've had it up in the air to remove the resonators and they are upstream. The mufflers are the last thing before the tailpipes.

 

Mufflers quiet exhaust noises while resonators tune the exhaust.

The Hellcats have a mid-muffler and rear resonators similar to the diagram:

Fair enough. I removed the mid mufflers then. The resonators were on my GT350. I still have the cans or resonators by the exhaust pipes, it was the mids I had removed. Sorry about that stonewall

I'm thinking we may have scared the sh*t out of Viper Chick

 

^ Booky has it right, the only difference is you don't have a suitcase muffler, both the Challenger and Charger have round style singular (one on each side) mufflers. The valves on the exhaust system are about where the #7 hangers are shown and easy to see from under the car. Then our exhaust tips are what shows out the back.

 

I think the issue is in that people use the names for the parts wrong. Engineers have re named things. And created all kinds of confusion. A muffler in a sense is a Resonator when designed as a baffle less can. Chevrolet back in the 60's had a chambered exhaust that the entire thing functioned like a resonator. Engineers need to stop re-naming parts and stick to designing them! Most have no mechanical aptitude at all.

 

I think some of the confusion muffler/resonator is historical. Somebody posted a diagram of a 197X Challenger which showed the muffler and resonator designations switched vs the current diagram. So those familiar with the early generation Challengers may remember that terminology.

 

Straight pipes would solve all the confusion!

 

Y’all are hilarious! And yes, I’m more confused. I can’t see the diagram that Booky posted. All I get is a “pay your photobucket bill to post your photo” or some message to that effect. See? Mike02z and stonewall have both made contradicting statements. No wonder guys never ask for directions or read them.

And mid pipes? What the heck are those? Middle pipes? Like Middle Earth? Is that the technical term? Hubby said I was thrashing the Viper too much so he took it away from me. All I did was make the rear tires bald. Nothing more. I didn’t redline the car. Ever. Lol.

I think the Viper only bites you when you’re being a douchebag driver. Other than that, it’s a fun car. Way awesome to drive with high heels also! I can reach the pedals!

Bing, Bing,Bing! OK, that's me

Terminology is a PITA. This is just for the Challenger Hellcat but likely the Charger as well.

Hopefully this will finally clear this up for you.

Within the light green circles in front, those are the catalytic converters
The red circled item is the x pipe
The blue colored items are the mid mufflers
The orange circles, towards the rear of the car, are they exhaust valves
The pink circles in the back are the resonators

A lot of members remove the mid mufflers and leave the resonators.

I hope this helps!

This just confuses me because my car doesn’t have the suitcase looking junk attached to exhaust piping. One picture looks different from the other. In modern Dodge Challengers/Chargers, which picture is more accurate?

Keep in mind that there is an exhaust pipe on either side of the engine. The picture I posted is what the underside of my 2016 Challenger looks like.

Good morning VC, booky is right on the money. Have a nice weekend and have fun

Take care. And nice to see your thread

 

Wait... the dark grey ovalized cannisters look more like mufflers and the cylindrical thingies in the middle of the whole exhaust set up next to the X-pipe looks like a resonator. See this is what makes my head spin

 

The dark green circles are around the Catalytic converters. The two items circled in blue are the mid mufflers.

 

Just take it all out from the green all the way back .And replace it with the mufflers you want .

 

Don't forget the exhaust valves. If you just replace the whole exhaust, and there is no provision for these, you will get a CEL. You'll also lose back pressure. While the exhaust will be loud all the time, it won't build as much boost. Less boost = Less power. A wide open exhaust is not always a benefit to a Supercharged engine. Just my opinion though.

 

Thx all! Clear as a colloid!

 

LOL The problem lies in that everybody that has posted is probably from a different decade. Terminology has changed over the years. Function is the same, but people in different age groups do not always speak the same language. LOL Peace.

 

stonewall you probably are more correct than right about that

Omg you’re 50?? So ol.... umm wise!! Lol Mike02z don’t feel bad. I’m reaching a milestone birthdate in 1 week and kinda stressed out about it.

My generation just calls it an “exhaust”

 

Hey Viper Chick. Quite a stir you caused . Actually very entertaining to see how terminology is interpreted so differently and even impacted by "generation" of the car nut.

Let me take a shot...if you are looking for an easy, economical way to change the sound of your exhaust system without creating drone then

...remove the cylindrical things that are circled in blue in Mike02z's post (mid-mufflers, resonators, whatever they are called) and have a section of straight pipe welded in their place.
...leave the rest of the system alone.

Fellas...is that correct? I always thought of that process as removing the resonators and keeping the mufflers. I've considered doing that also, just haven't heard what it sounds like. Any before and after clips out there?

 

Yes, that is the best way to go. I'm removing the things in the rear people call resonators. I want the below tips so I'll replace the resonators with a piece of 3" SS pipe.

See Hayabusa? “whatever they’re called” lol. One of my friends called me with conflicting info on exhaust info and I gave it to him - the info I mean but there’s an issue with naming parts, which is why I brought up this thread in the first place.

You can tell where I’ve been by either the amount of trouble that’s been caused or by the amount of drama that exists at any given time and space. Hope you don’t mind me inserting some quantum physics terminology there
