Resonator vs muffler????

Hi guys I'm new at the forum, I have a 11 limited 5.7 GC and I'm thinking to mod my oem exhaust sistem. I've read lots of posts but I'm really confused about wich one is the resonator an wich one is the muffler. So at the back are two little bottles in each tip and at the middle is like a big suitcase. So when you guys talk about installing a xpipe I have to remove the suitcase and keep the ones at the back???? Confused!!!!
Thanks in advance!!!

Re: Resonator vs muffler????

The boxes at the back that the exhaust tips come out of are the resonators. The big "suitcase" at the middle is the muffler.

That's wrong. Mufflers are in the back to connects to your exhaust tips. The resonator is in the middle and is usually quite big.

Well they are wrong. You obviously have never done anything to an exhaust system. Muffler is always in the back and resonator is in the middle.

Re: Resonator vs muffler????

Rewind; I'm glad you know more about these vehicles than the people who designed them. Everything I've ever found about this exhaust system also calls out the larger component as the muffler. Regardless, there is hot debate as to what the muffler/vs resonators actually do for sound reduction.

Not saying I know more. I'm thinking it's a typo and know Chrysler I doubt they go over it in fine detail. As for noise and what each one does, my past experiences with exhaust is the middle piece keeps the drone low. That piece has the biggest impact on quietness. The mufflers and the end give a nice sound. If you reace both it makes a lot louder and a good rumble but you will have a pretty annoying drone even at cruising speeds. My .02 though. Some people like it. I prefer a nice rumble upon acceleration but to cruise in comfort.

i took my limited 2014 with factory duels to the shop had him cut off the back 2 and replace with straight pipe, now i just have the big one in the middle, and its not real loud but has a very nice sound, and i gained 1 mpg and a little more power, sounds good !! i highly recomend it

nope not a typo brother. take it from me, the reso's on the jeep are at the end, the muffler is always and will be the larger component as it does the most to reduce sound. resonators are designed to further enhance sound and to reduce drone. As someone who has fabricated many exhaust systems for people in the past, I do know what I am talking about.

Yup Jeff is right the muffler is in the middle and the resonator is right before the exhaust tip. Haven't you ever heard the term suitcase muffler? The resonator is much smaller than the muffler. The muffler reduces most of the noise and the resonator cancels any drone.
