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.
