Not sure if this was for me but yes, original resonators in place. I wonder now too if something as simple as moving the muffler forward would have helped? I note on installing that j pipe the instructions say if the drone doesnt go away, move it forward one inch..try again..move it again.

Darned if i can figure out who I'm going to ask to lean out and move the J Pipe at 65mph? [emoji16]Maybe @Wild one ...earn that name!

Yes it was.
This muffler might do what you want.

Install sound deadening inside cab. Get benefit of peace and quiet inside and let everyone else hear your rumble outside

Might try swapping the muffler and resonator positions, though it can be a pain depending on hangers.

That was in the back of my mind. Not something worth all the trouble to me

Recently put a Magnaflow catback on a 2500 with the 6.4L. Had horrible drone in the cab from 1400-1900 rpm. After a lot of research into different methods to cut the drone, I decided to try an auger exhaust insert. (https://www.speedwaymotors.com/Speedway-Auger-Style-Muffler,1736.html) They're cheap and easy to install. It cut the drone out completely in the cab, and kept 90% of the exhaust note out back. I did not notice any decease in performance. If the fit of the auger is tight when installing, it eliminates the need to tack weld it in place. I installed it in front of the muffler.

I like the price!

If theres one thing Ive learned over the years is that drone is subjective and cellphone shot youtube videos do not do justice. The exact same system will have guys saying its the best ever with absolutely zero drone and the next will say it droned to hell and back and he hates it. All sorts of differences come into play, namely driving style and gear ratio. Oh and the terrible MDS, if this is still active on your truck, hello drone!

The absolute worst droning truck Ive ever driven was a nissan titan 5.6 v8 with a magnaflow 14" small round **** side exit before the passenger rear wheel. Would rattle all your teeth and felt like my head was going to implode from the drone. Im pretty sure it had a k and n too probably didnt help.

Meanwhile Ive got my super 10 dumped over the rear axle (no resos no mds) and I find it perfect and simply musical, burbling down the road. I can understand that some people would say it drones but its actually less drone than when I had a muffler delete with factory resos. For me she just purrs, sometimes I even wish it was louder haha

Lol yep I had a 09 titan cc with the 4.10 tow, LT headers, high flow cats, MF 14 for a while then a 22, MXP, uprev tune- it was soooooo loud!!!! That truck did me in on loud exhaust!! My 18 sport hemi with factory sport (not the mopar one) exhaust sounds just right to me now. My neighbors threw a party when I sold that truck lol because I left for work at 4:30 AM

Well, I have found a further improvement for my drone issues. Note I said improvement not 100% solution. But, I'm pretty happy how it turned out. I did more research last night & came across a post where a guy had a van with bad drone & says he solved his problem after banging his exhaust pipe in various spots until he found a spot that sounded different & rang a bit. Then he put some kind of rubber piece around it and clamped it & claimed it was gone. I was sceptical..but interested. I'm high on problem solving/have lots of time/have little money so found a chunk of 1/2" wide rubber gasket & plastic zip ties & my hammer & damned if that chunk of pipe just after the crossover posts the cats doesn't ring. Like for 2-3 seconds..vs a dull thud elsewhere. And the ring is at the crossover as well. So I put on that gasket & hit the pipe in that area & the crossover pipe. No ring! And hit the highway. Ok, the drone is still there. But its changed. A) The volume of it has reduced B) Where yesterday it was solid from 1500 to 2000 rpm, now its next almost gone except from about 1700-1800 rpm!

So off to Canadian tire I go and buy a fiberglass stove gasket kit. 3/8" rope x 6 ft and 2 stainless 4" dryer clamps for less than $14 canadian and 10 minutes later, done. (See pic below)

Off to the highway again. About the same result as the temp rubber gasket but a bonus now. I notice on startup & driving around town, the tone has improved! There's a deeper note to it I've not heard before. And I like it! That rope btw is guaranteed up to 1000F so I'm not concerned about burning it up. I picked up that trick using it to wrap baffles on my motorbike exhausts to modify a barky exhaust tone that was hard on the ears.

Now that if freaking interesting!!!!!! Thanks for telling us about this!!!!!

Definitely made quite an improvement. I'm surprised/not surprised really. Hitting that pipe was almost like a tuning fork! Now I get that the insulators on the hangers probably get rid of a good bunch of that, but if that exhaust is vibrating & resonating and you change out the muffler but not the exhaust, I totally buy how you f*k with the manufacturers design. I remember when I had my suzuki big twin c90 and found the stock pipes too tame so I went to Cobras. Big name, designed for the bike so what could go wrong? What a mistake. The motor sounded like a tractor & harsh without pleasant notes. Just loud. So I added baffles. Better tone but still very loud. Then I wrapped the baffles with that fiberglass rope. More civilized tone, deeper and not quite as loud.

Its a science for sure!

PS- the shop reached out to me for my opinion and has offered to give me a credit back on the Walker bottle & install muffler of my choice. I've asked him if he will honour the offer if I come in before August 1st. I don't think its fair to ask them to refund the bottle a year from now. My thinking at this point is to get the drone free Solo mach 44 and be done with all this. Its just extra money on top of what I spent I can't do right now. But I feel I have a reasonable solution in the meantime!

What shop in the city are you using Terry

buddy guy · Jun 5, 2020

Carline Automotive in ne calgary behind the Canadian Tire. Was owned by Rick Withell. My understanding is his son Cam owns it now but Rick still works there, I've seen. Can't remember exactly how I chose them last year. I do know they were highly recommended.

I remember originally going to an exhaust shop I think in East Lake area. The owner wanted to do a custom exhaust only for 2000 bucks BUT said changing exhaust would break my warranty. I already knew that was not the case if you did only a muffler or catback but he was stubborn about it so I never went back.

Resonator on and solo delete will actually not be loud.

Loud is very much a relative concept. I'm still not set on the solo mach 44 as I read tonight that the mach 40 is designed to work WITH the resonators which I'm def leaving on (the factory ones) to give no drone. I read elsewhere the delete with res left on isnt bad either. Then 2 seconds later you read other experiences that are totally contrary. So frustrating

@gdawg55 had a dynamax ultraflow 6" round installed with magnaflow y-pipe and is extremely happy with it. He's tried all the mufflers you talk about.
He did post a video of it. Quietest muffler in cab he has had other then stock

Well having let this muddle around in my brain for a day +, I've decided to call this muffler journey good enough for the time being. At $300 a pop it seems, trying to find perfection I'm not prepared to spend one more dollar until a component in the exhaust system HAS to be replaced. At this point I'm just shy of 600 bucks in with a good level of improvement. Another 200 to 300 bucks later to satisfy maybe my OCD?, isn't worth it and its probably going to **** me off thinking I spent almost a grand to "maybe" solve the problem completely.

It helped to talk to the Solo sales rep about both the mach 40 & mach 44 mufflers and he was insistent they were both no drone systems, yet his next comment was basically that some pple confuse drone with exhaust. I don't doubt that but I know whats drone & whats not. Anyway I'm still not 100% confident even the Solos are drone free in every case. Corsa is the only 1 that comes up as drone free always. 1900 canadian for the catback system. Before welding. And sounds like a Ferrari? Mmmm not going to happen.

It also helped to talk to the installer again about how I was maybe planning to proceed (a Solo muffler) and I said so to be clear I'd get a credit for the price of the bottle & no charge for install right? (He's the one who said if you aren't satisfied we'll make it right!) And he said welllll I'll probably have to charge something. And I thought...here we go. I'm done.

Yes sir. I'm still running the dyomax with no plans to change. My impressions of it haven't changed except that I might like it even more now that it's been on my truck for several months. I've been through a bunch of mufflers and the 6" round dynomax has bested them all for what I was after. Deep tone, medium loud outside volume and very low internal cab noise. Still no drone with this set up and I'm amazed by that. Never had a round muffler before so I didn't know what to expect. I was pleasantly surprised to say the least.

LT headers got rid of my drone ;-)
