## Customer Reviews

### ⭐⭐⭐⭐⭐ Well built and quiet, but LONG!
*by A***. on July 1, 2025*

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.

### ⭐⭐⭐⭐ Muffler with Repacking Ability
*by B***N on April 21, 2013*

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.

### ⭐⭐⭐⭐⭐ strong well made and beautiful
*by M***H on April 10, 2023*

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
