wrapping baffles

What effect does wrapping baffles have to the noise levels & Tone?

I am thinking of popping my "HK Quiet Baffles" back in and wrapping them so that I can use my bike at silly hours of the day. Any suggestions, personal experience, preferred products or advice would be welcome.

Not sure about the cruzers Dave but i wrapped my pro pipe baffle with extra wadding and it did nothing

so tonight I took the baffle out and did the Bluesman mod


That has made a hell of difference, still deep and thudding without the volume
and no one can tell

do the cruzers have removable baffles so you could get some wadding in the exhaust _

Hi Dave the advantage we have with the cruisers is they are detatchable.You can pack them until they will just fit back in,use a fine wire to tie them with.I use a bit of tipex on the inside of the exaust first to make it easy to put the baffle back in the right place for you only have one little grub screw at the back.If you wish to quieten them even more,you can make a baffle to go into the baffle or make a new one all together by making the exit hole smaller,this is the way I have been experimenting.It is not to bad for me as I live in the town centre and it is mainly busy day or night so not to much to worry about.I have seen baffles made from sink components the drain part.Will search for the link if I can find it.

Yeah the baffles that are made from plumbing stuff uses a sink drainer and pipe, a mate of mine made one a few years back.

Problem is that if I started reducing the volume of the exhaust as in the Bluesman mod or similar I will loose power and I really am not happy to do that! I was hoping that someone might say that if I stove roped my HK quiet baffles that would make a noticeable difference but do far no one has

Go for it Dave or use DB Killers to try and get the desired effect,cant talk from experience but I would not think they would loose you that much power.

I have "DB Killers" in already in the form of the HK Quiet baffles.
I will get some stove rope and wrap the I think, I will report back on the resulted differences at various rev ranges by checking with the DB app on the iPhone.
Cheers

Stove rope is pretty good - get the tape version from a heating supplier - I think it's called chimney tape. Wrap around the baffle tightly and bind with wire (twist with pliers untill it snaps) - I use 3 wire rings on my HH baffles which are about 4 inches long. I have got them in at the moment. The exhaust pressure prises the rope apart gradually so the pipe gets louder over time so you may need a 2nd application. I took out my mesh and packing pipe liners last week and reinstalled the baffles with stove rope. Like you Dave, I keep experimenting. I am planning to do another mod soon. I will fix the mesh/packing tubes on to the HH baffles and fix this in the pipes with the regular screw. Will post pics if I do this. I am constantly changing my exhaust note and never seem really happy!! I think I posted an advert a while back but it appeared to be a broken link (shame)for an handlebar operated servo which meant you can vary the sound at the flick of a switch! Wow wouldn't that be great! For the meantime some kind of internal wrapping seems the best way to go. I do like thuddy pipes rather than metallic sounding ones. Pipes sound different when you are riding compared with what others hear. I always seem to prefer bikes that go past but then It's different when you are sat on the thing! Hey ho!

PS If you want a quick way to drastically reduce the volume as you ride away from home - make a couple of wooden plugs from bits of batten, hammer them in, ride a hundred yards in near silence, stop, wiggle them out and put in your saddle bags and continue at normal volume. I did my early morning gettaways for a whole summer last year using this method. As long as a bit of gas can escape, they will be fine and soooo quiet! Looks a bit stupid but very, very effective.

Good idea on the quick fix to get away in the early hours John

Thanks for the tip on the chimney tape, I will definitely give that a go. The problem I have is that I love the tone of my V&H exhaust as it comes but the DB levels are way to high for suburbia. When I have the HK Quiet baffles installed I still love the tone and I very happy with the DB levels but it is still to loud for early mornings & I just need another couple of DB's off the top so I will get down the chimney shop asap.
