EMGO Chrome Wide Mouth Dunstall Muffler 27-1/4&Prime, Long 80-84050

This is VERY long and VERY quiet. If you are looking for a way to shut your bike up for city cruising, this is it. Loud pipes do indeed save lives, this is not that. Also the build quality looks great, I'm not going to cut it open, but it looks a lot better than the $35 muffler my facebook marketplace "restored" bike came with.

Basically is a shiny, kinda heavy (although that might be normal) muffler I put on an1984 Honda CB125s. Fit the small exhaust pipe I had (1 3/8 inch I think) and was the cheapest muffler I could find, with shipping. Had a shorty muffler on before, packing burned out and pretty loud, about 120 DB. Before repacking this new muffler, not much quieter, just different tone. Looked for tips on repacking online, one guy said wrap steel wool around baffle cage and then do fiberglass packing (helps save packing from heat). It's now quieter, which I wanted, although definitely not silent (my sister can hear me leave in the morning and she says it's loud). Well, I tried... although I wonder if a silencer muffler would have been quieter.Anyways, I wish some company would have posted how wide it gets at the end, and not just the length of 27 or so inches. It's not obnoxious looking on my bike, but shocked me when I took it out of the box. The width at the end is 4 inches; however, this muffler is Repackable, unlike others I saw among the cheap mufflers.Another thing. It comes with a sticker that says something like "made for pre-1983 motorcycles and does not conform to EPA sound limits" or something like that. That would of been nice to know, although it didn't affect me in attaching it and I don't think my state has a DB/sound level limit. This info wasn't listed on any site I used.

chrome finish is fantastic and the muffler is thick and heavy, unlike many other thin like walled aftermarket mufflers. the baffle is removable from the front..thats so nice. no need to pull the muffler off to rewrap the baffle or add more silencing material...or even to remove it entirely and run it straight...for awhile...only thing i must return it. am so sad about that. the rear of it is 4.13" [105.1mm] around at the rear where the baffle is located. however it is NOT 4 inches [as stated in the description at many places] instead it is 1.70" or 43.2mm at the front where it connects to a stock down pipe or collector. my stock 1979 gs850g down pipe is the SAME od as this pipe...so i would need a coupler welded to the muffler or the down pipe or small dia. collector...then i could use the very strong NICE clamp to connect it. problem is i have 4 down pipe attached to and exiting a huge 4.50" diameter collector. so noway this will work for me. i thought it [as described] was 4" front and rear, but its NOT. if 4", like they showed in many descriptions, i would of been able to make it work. i hate to return it...its so well made! got no choice tho. if you have a smaller collector or down pipe you'll be ok with this muffler. it will work great...there are two extra reducres 1.46 in [37.1mm] and one 1.49in [38mm]...its a shame i have to return it...it should say 1 1/2 in intake to 1.46in ...instead of saying its 4 inch entrance opening...i finally decided to keep this one and just cut a piece of the muffler from hedder end down to the 2 1/2" mark...used a exhaust insert and connected this muffler to the hedder collector. i was able to adjust the length to stock length because the hedder collector was 21/2" its whole length. i just welded the two together [to match stock length] with 1/16 welding rod and I am happy. there now is NO popping noise and i CAN control the loudness too. i can adjust the sound by removing the baffle and packing it or even welding part of it shut with a metal tube sleeve. super great muffler and very adaptable

I've been through a few of these now, they all have the same issue, the metal is too thin at the mount, putting even a modest amount of tension on the mount bolt causes the metal to deform and ultimately tear out. They also make a terrible seal where they slip over the header. They look good and sound good other than the sound of the leak at the header.

I like the look of these mufflers very much and from a strictly cosmetic standpoint they are excellent - a big improvement over the extra-long cigars that Triumph put on the stock bikes. However, I could not mount them to the standard Triumph muffler brackets and had to use the ones provided by EMGO, which do their job well but are a bit ugly. The real reason for dropping to 3 stars is that the packing material around the pipe inside the muffler is very flimsy and poorly attached. I opened mine up to see what was in there and was surprised to find a few tattered rags of insulation. So I replaced it with fiberglass muffler packing material (the kind that comes in sheets about 1/4 inch thick) and now the pipes look AND sound great. EMGO needs to pay attention to the construction of things that are not easily seen on the surface.

be prepared to do a lot of metal and pipe work if you have 1 3/4 inch pipes. It does not fit although in the add it says it does.sounds about the same as when there was no muffler...
