I’ve made them myself using pre-bent pipe sections and welding, and also buying a piece of pipe (1.65” ID X 1.75” OD x 8’) from a muffler shop, and then have them bend the pipe to match a stock header, weld on the flange, and be sure to have your bike on hand when it’s being bent so you can check to insure it will bolt up properly on the bike. Mine required 2-3 adjustments to fit it, and that’s why the end of my pipe needed to be longer to get beyond the distortions so my muffler would fit properly.
I believe the muffler shop had to order the pipe since it was smaller than the sizes they normally carried for cars/trucks.

Yep, replacing the restrictive muffler is good. That is why the Dyna muffler is such a popular choice. It is cheap, easy to adapt, sounds better, and flows much better than the stock muffler. DBM's modified automotive muffler is the next step above that but requires a bit more work. Worth it for the sound and performance though. Sound is similar to the Dyna but louder, and it flows better than the Dyna.

Exhaust pipe length doesn't matter on these when you stick a muffler on the pipe. What does matter is the pipe inside diameter. The stock pipe is too small when you get into more serious performance mods like a bigger bore piston, more compression, hotter cam and port work. RAASK made a 1.5" ID pipe and MAC had the whopping 2" OD x 1.8" ID pipe. As far as I know no one ever made a pipe between those two sizes. Having a custom pipe made up from 1.75" OD tubing will put you in the sweet spot for exhaust velocity for a stock to a fairly hopped up engine. When you tread into DBM territory with engine mods the bigger MAC pipe begins to shine.

it ain't restrictive with the baffle removed. sounds great. there is just a little drone at highway cruising. i considered the dyna muffler but hearing it on videos i dont really like that sound. delkevic sounds better to me. I guess i will find out. one day. not a top priority rn just in the research phase.

Fast650 definitely knows what he’s talking about! No comment about, “it ain’t restrictive with the baffle removed” especially in light of the other information presented in this thread and several other exhaust discussions (like DBM’s muffler shootout).

Video sound is never good regardless of whatever muffler. That said, the Delkevic sounds like crap to me. To each his own I guess. Cheers!

Removing the baffle definitely let's it flow free. Rejetted the carb to compensate, but that was needed anyway. May consider to just leave it alone because I like the sound and she runs great. I can deal with a little drone at 70+. Have you heard the delkivic in person? I have not seen another savage in person so I have no idea what they sound like with dyna or delkivic in person. I am purely working with video sounds. There are quite a few guys on YouTube and one guy on here who vouch for it and say the delkivic sound very deep and nice. Who knows. It's not a priority at the moment but if I ever get it I will definitely update y'all. Muffler will be the last thing I do before the trip next spring, if I swap it.

I’ve only heard the dyna in person. Not the Delkevic. So I can only go by video sound.

Modifying the stock muffler has proven fairly successful the way DBM did it. And I’ve heard other people like the mods they did to it.

I don’t mind the quietness of the stock muffler, but the high pitched whistle is pretty annoying (mostly at idle speed).

I think just about any muffler is going to drone at highway speed on a thumper. Turning 4000rpm at 60mph is going to drone…. And it’ll drone even more as you climb the rpm ladder Wink

Give it a shot when you get to that stage. It’s personally more than I would want to spend when a dyna sounds pretty darn good in person and can be had for like $40 plus some extra hardware, etc. The dyna sounds pretty good at highway speed (and you won’t hear that in many videos).

True. I suppose drone will be inevitable. Hopefully I run into someone with a dyna muffler one day. Wouldn't mind hearing it in person.

Sound check…Testing 123…

Let’s let it idle on the side stand and starve the valvetrain of oil pressure. My first criticism… Shocked

It sounds good idling, but when he gives it a little throttle, it sounds like somebody is holding a screwdriver against the spokes of a spinning real wheel (best description I can come up with on short notice). It’s not for me. And who knows what it sounds like rolling down the road at 50-70mph. Maybe the “clattering” tone goes away.

Go with the tried and true Harley Dyna muffler. There’s lots of good info in the Tech Section about the HD Dyna. I have one left for sale (like new, pristine condition). See link below.

Who knows how that Aliexpress turnout muffler behaves or sounds, and installation may be funky. I don’t know anyone that’s tried that muffler. I think you’d be in uncharted waters with it for installation and tuning the carb.

I will take your advice. What will the Dyna muffler set me back ?
Shipping might be a problem

PS, from what I can see there is a connecting piece between the two harley dyna mufflers, what happens about that ?

Here’s a link to my recent installation. There is also more information and other methods on how to mount the Dyna muffler in the Tech Section.

My install —> http://suzukisavage.com/cgi-bin/YaBB.pl?num=1726756292

You will only use one of the mufflers. Don’t worry about the mounting rod used on an actual Harley. See the muffler I listed for sale.

You will need a few other items to complete the installation. I included links to some of the items and referenced others. There’s a couple other things like channel bolts, nuts, and washers. And you may need a new gasket that goes between the header exhaust port and header pipe (depends if yours is still in good shape or already trashed).

The last Dyna I sold went from here (Houston) to Alabama. FedEx 3-day shipping was $6.99 using my discount shipping app. Dyna + Shipping was total $52 for the buyer. That’s pretty close to what you would pay for some unbranded and unproven muffler shipped from China via Aliexpress.

The extra things you need will run about $30-$40. See the links in my installation post to see a few of the extra items. I didn’t list links for the fasteners I bought at Ace Hardware. The exhaust coupler I used to connect the header pipe to the dyna muffler came from Autozone (like $4).

PM me if interested. You may have to have 10 posts to message me. I can try to message you if that’s the situation or you can keep posting questions or commenting around the forum until you hit 10 posts. (I’m up to like 1500 posts/comments. It isn’t hard, but I know I’m annoying sometimes. lol)

I bought the other muffler from the same set he has left. It is in good condition. I am just waiting on a few additional pieces to put it all together. Total cost for me ended up being right around 110. But again, with a random muffler from China, you are looking at potentially more because you are left to figure it what odds and ends you need to make it work. I will update for sure on the installation once it's done.

It looks perfect, its a shame it's such a process getting all the parts together. If I could get everything I need from one place I would do just that. Canada post are on strike right now and the chances of getting parts from different sources will be impossible.

You will have those issues no matter what you get unless you get something expensive like Delkevic. Any other muffler not specifically made for this bike will require additional pieces. With that said, you can look into modifying the stock muffler temporarily. I removed the baffle with a basic hole saw bit and rejetted my carb. It's not ideal but it's far superior to stock sound. It can be a little annoying at 70mph though. This could be a cheap temporary solution until you can get the parts necessary. There are other methods to modifying the stock muffler as well which include drilling holes instead of removing the baffle all together. Try that first, may be a better sound than removing it entirely. At least temporarily.
