Sounds so clean and good volume

Sounds fantastic with your wrap job!

I wonder if the super tight packing of the original baffles prevented them from dampening a lot of the noise.

Excellent video, I've fitted some V&H's to my Rogue and they are loud and now you may have given me the confidence to repack them myself

That Indian is a BEAUTY!!

That sounds good

To make them quieter turn the baffles round , the open ends of the slits should be facing the engine and not the way you have them fitted

Sounds great! My Scout is still in waiting on the Indian stage 1 straights, and the sound I am hoping to get is what you have with your re-packed exhaust. Throatier than the stock exhaust but not ridiculously loud. Great job! Thanks for sharing.

Way quieter but still a beautiful tone. Thanks for giving me the link. I never got this notification.

Lots of people might not understand why you’d want quieter mufflers but if you’d had that ringing in your ears from days of riding you’d know exactly why. Great topic Chris, I think I’ll do something similar for a certain multi-day ride next August. The ear that got hurt - was it the same side your pipes are on?

It's really not bad. My only concern is that you reduced the diameter and you could have lost 3, 5, 8 HP power... You have to check if you notice any difference in the highest RPMs, when you want full power.

The loudness is coming through the end of the muffler, not through the baffle. If you want quiet. You don't want to obstruct those holes. By packing tight, you're allowing more flow through, kinda like a straight pipes. My Rhinehearts DBX had no packing from manufacture and they are quiet. I even welded and pluged some holes to make it louder.

i bought some LAF pipes and made my own baffles , its a fun time trying to tune sound , you need to find a good balance , nice job 👍 ,looks like you did good ...

Just bought a Road Glide with the 103, Rush ceramic coated headers and their "Big Louie" 4" slip-ons with 2.5" baffles. Loud as hell. A look down the baffle shows the packing was removed or has blown out. I use the same Moose Racing material you have on my built Guzzi LeMans and it does take the "bark" out of the note. I'm pulling the Rush baffles and repacking this week.

Should have tried putting the baffles in the other way, with the internal openings facing the engine. I had a straight through muffler like that and in the instructions it stated if you wanted it quieter, holes towards the flow, louder the other way. Love the bike!

Ok.. The theory is quite simple: if nothing breaks the sound waves the pipes are loud. If nothing dampens the sound waves the pipes are loud. So you need a "not full surface".. therefore the holes, which break the sound waves bouncing back and forth. And you need layers of soft material to absorb them. Fiberglass is heat resistant so it is used for that. Whatever can resist 200º-300ºC ca. is ok. In theory you can use cotton fabric or wool too, outside the fiberglass layers... If it doesn't burn it's ok. (therefore you can use masking tape outside. The temperature on the outer surface of the fiberglass is not that hot and even paper masking tape doesn't get burned). Some baffles have that further piece of metal straight through the diameter, it goes towards the engine (against flow) and its role is to break the sound waves at the beginning of the packed pipe. If you turn the baffle around and have it at the end of the pipes it doesn't work as it should... Pipes are therefore louder. Not all baffles have that, but you can create it, for example using twisted steel wire straight through the diameter of the baffle. Then it's important to have enough space (volume) to let the combustion gas go out: larger pipes (larger baffles) allow better combustion-gas outflow so you could gain some HP, but only up to a point. But larger pipes they are louder, of course because the sound waves bounce out with less resistance. Smaller pipes (thinner baffles) could reduce the outflow and you could lose power. But they are more silent, because the sound waves bounce more and get absorbed more. You have to pick the right balance. Of course the softer and thicker the absorption layer is the softer is the sound (because you cut the higher frequencies.. high frequency waves bounce more and get caught - absorbed - more on their way out). That's for the theory...

Well good job! Will have to do something similar on my Scout Bobber with HP Corse exhaust. It's ok when I drive but too loud for others...

I got the quiet baffles for Mrs Rebels' Scout and they don't sound much quieter than the standard baffles!

I love my crushers but I thought about modding my stock mufflers at some point. Good to have options

Trying to quiet my Rinehart Racing pipes too, and might go your route. And mostly impressed that you live in Italy. I grew up in Rome (dad worked in the Embassy), and man would I love to move back. Rock on man, keep riding...

It still sounds good to

Well nice improvement about the loud save lives you still have a loud one so thats ok

WOW, I have to admit, that sounds better than my Softail 2020 with Vance and hines Stage 1. Congrats. I will probably do the same repacking. Thanks for the inspirational video! Would be nice to know what the actual decibel levels are at.

Sounds better, not wimpy like stock, and not raspy like the regular baffles.

Привет. Hello! город Красноярск смотрит. Veri good

I think you achieved something very good !?

How is it sounding now? Is it still the same or it went back to the loud tone?

Like it more than and HD...?

I’m trying to do something like this on a much smaller scale on a motorcycle. Does air have to pass through all that wrapped material?

Sir : what do you use to re tune the computer !!?? I brought mine to the dealer , cost me $$$ and logically now I am screwed as soon as I modify my pipes in order to make them quieter :(( thanks for all the help

Dear Sir: I am in exactly the same situation . I bought some superbe Screamin Eagle for my Nightster: a Hell of sound but even with earplugs it’s a nightmare . I disassembled them to find that the packing was burned . I tried to fix them with Fiberglas house insulation like I saw on YT, to no avail. So I bought the stock mufflers ... nothing good: they are also “burned”.. and it’s even worse because I did the Stage 2: and now I smell like fuel like hell... so I want to put back the screaming eagle put how the hell am I going to shut my panthère up!?? I am continuing to watch your video...

How much length let me thx

I bought fiberglass to wrap vance and hines baffle. Not sure what else i need. I’m thinking welding a small fan inside baffle to reduce more sound.

Is there a specific wire that u have to use? Or will any wire work? :D.

Hi ,no danger for the thermal tape on the inside?

Damn: just realized that you change the whole inner pipe so you can put more insulation ...??

Steel wool and wire

Looks like the entire surface of the packing was wrapped with tape. That would prevent any absorption

All this and we dont even get to go riding with you???

Way to loud. I guess bikes are loud so people can hear them coming. Otherwise I would wish they were no louder than cars

Haha too quiet
