just wondering if anyone else has replaced baffles with quieter ones

I am interested in getting a set and trying them

 

but you right, not much out there

 

Thanks Fat tony

Big City Thunder make some to suit the Big Radius pipes, see bottom of this page headed "For curved pipes"

http://www.bigcitythunder.com/pages/product-fit.html

I looked into this once as a contingency in case the Big Radius were too loud but after hearing them I reckon they're just right, personally I wouldn't mess with the sound.

It might just be the fact that I'm used to them now but mine seem pretty mellow to me these days.

I recall seeing an example video on YouTube with a before and after of the Big City Thunder baffles, do a search on there.

Thanks KC & B

I was also thinking of wrapping the existing baffles with fibreglass

or some type of material that the muffler shop can suggest

I agree with KC the sound doesnt seem loud but here in NSW

the boyz in blu set themselves up with noise recorders ( they look like hand held speed cameras )

on main roads. So far I've only seen semis being pulled up.

I think compliance is 94 DB - to give you an idea the screamin' eagle slip ons are around 96 DB

not sure if it gets measured when idiling or reving at a nominated rpm

I think there is an ever growing market for these things out there. What about an automated baffle

where you can flick a switch and it restricts just when you want to.

any engineers in the HD forum family ? 

 

Fat Tony,

Yeah when it comes to the fun police any pipes other than stock will be defected for noicse.  I had the SE Street Performance slip-ons on the Sporty which are so called 50 state street legal in the U.S and I still got defected for noise with those.

With your last comment about a pipe you can switch, there is such a thing around I recall reading about it.  Maybe someone can remember what they are called?

ive tried just about every "quiet" baffle available for big rads none make a change, those hard core baffles do absolutly nothing. i custom made fiber glass wrapped baffles out of perf tube they cut noise to similar to SE slip ons

Thanks Jordan

 

can i please ask did you make a "new" baffle or just wrap the old one

 

thanks

 

Fat tony

the O/D of the stock baffle leaves no room to wrap anything around em, the fiberglass matt is 4 or 5mm thick, i used some 38mm od perf tube got it rolled to the radius of the pipe, lathed up some rings, but the best result is to put a cap over the inner end of the perf tube and ran the tig on the ring about a third of the way down. thats the only way i can get em quiet, the aftermarket stuff is all crap, running tape around the baffles i think will do very little. and will only last one or two rides before it burns out
