Leave them on unless you want your truck to sound like a Honda civic.

It won't hurt anything to take them off.

Nope not a Honda [emoji41].

Resonator has nothing to do with emissions, unless they consider noise a form of pollution...lol

The delete pipe with factory muffler sounds just fine.

My delete pipe has an electric cut out installed in it, so factory quiet when needed and obnoxious when wanted.

 

Emissions....thats crazy!! It is a sound reduction device only. As the posts above state, has zero effect on emissions. It is embarrassing to have answers like that come from the manufacturer or dealer. IMHO all that talk to the public should have at least some education on each vehicle and it's common components.

This no resonator no muffler stock cats

Thanks everyone for the feedback. I'm gettjng it done this weekend. I'll post a video.

 

I deleted the cats and went with solo down pipes with resonators

 

I did this and deleted the factory resonator. Sounds a bit louder at idle, noticeably louder at WOT but not to crazy..Still sounds like a turbo v6 though, but not "fart can E" like a ricer.

 

just put a 3" resonator on and that way you have the best of both?

 

I agree with 2Canches ... the resonator delete does not sound like some Honda Civic with a fart pipe. The unique firing order of the 3.5V6 (compared to other manufacturers V6) give it a unique sound. Actually more like a Triumph Rocket III, which I like.

ExoFx does have more experience in the sound of the 3.5 Ecoboost, because he's usually behind them when he races them with his Ram.

 

Smart enough to not even try lol

I deleted the stock exhaust completely but kept the Res with a turn down. Thought id share.

Feels like it gained some top end.

 

I think it sounds great. Wish I could hear it live.

 

I have gone with the super cheap mods.
AEM filter, $40 on Amazon.
Deleted the Resonator today for $55 at a local muffler shop. 2 cuts, straight pipe and 2 welds.
Still have the stock muffler.

Sounds the way I want it. A little more growl with more whistle.
Obvious difference with the windows down.
Now I know folks can hear the turbos spooling.
Good enough for me.

Might get a muffler in the future but I'm in no hurry.

 

Did you leave the flex pipe on?

Yes, he cut 2 inches from each side of the resonator and replaced it with straight pipe.
Other than that 18 inch section, it's stock.

 

so you still have a restrictive funnel.

Remove the flex pipe then report back [emoji33]

betcha you will like the new difference !

Will do. thanks.

 

subscribing for the findings

 

is the flex pipe part of the resonator or part of the catback?

 

It's between muffler & res

So what would replace it, a resonator delete or a catback?

 

A custom 2.5" or 3" straight pipe.

So its not part of the catback or resonator pipe? Just a res delete or just a catback that doesn't have the resonator section won't replace it?

 

It would be replaced with a cat back system. I believe 2canches is just saying that it is beneficial to remove the flex pipe with the resonator.

Edit: lol, he beat me to it.

 

Yes a cutback would replace it.

It goes

Down pipes
Resonator
Flex pipe
Muffler

Have a look under your truck if weather conditions let you

Its not built yet. I still have my raptor. Ecoboost coming in the spring(April)

I'm very hands on, I normally dont ask simple/dumb questions that i can figure out myself but I'm trying to get together a list of parts I want to start building up a mod pile for when the truck arrives. Without the truck being in my driveway its a challenge. I'll have my level kit for it this coming week. once I start demodding my current truck I'll start buying some more parts for the new one

 

No worries. Keep asking. We only try to help.

Unless you're one of ... Them [emoji83]

Thank you, OK so now I see that flex pipe is actually welded to the muffler. So any cat back system will get rid of it but just an off the shelf res delete won't. so a straight pipe would be needed to be welded on if the stock cat back is kept.

 

Wow, there really is a difference between the pipe in and out of the muffler.

 

Your right, there seems to be a pretty big difference!

The stock down pipes where it y's into 1 pipe is that 3" or 2.5" ? I know the res pipe is 2.5" but what about the y pipe?

 

Great info. Thank you!
