Are your V&H quiet baffles too loud?
I wanted, to make my Vance & Hines quiet bafflesa little quieter, to take the rasp off when you crack open the throttle. In my opinion it has worked and the tone is even deeper. The performance feels at least the same, i,ll let you know the dyno figures soon.
I,ve seen this used on other pipesin fact the pipe i used came from a BMW R1150R Remus muffler.
The pipe is 1 1/4" outside diameter, 2 1/2" long, with a bracket welded to the end with a 1/4" unc hole tapped in ittofasten inside the V&Hquiet baffle. The maximum length you could go to is 5" which could drop the sound more i,m not sure.
I drilled a clearance hole in the V&H baffle opposite to the existing hole with the backing nut as this makes any removal easier in the future.
I used the original V&H stainless fixing screws.

Can you expand a bit on this? You put the BMW pipe inside the quiet baffle?

Its a simple idea that many pipe makers use to take the rasp / edge off the top,its stillloud enough if a little deeper. Look at the end of most sports / street after market mufflers and theres a grub screw to retain a secondary baffle as i,ve described.
As it cost me nothing to make i thought i,d try it and i,m well pleased with the result.
This would work with most mufflers, the only possible change being to use a different size pipe to suit.
Hope this helps.

Rhubarb,in the attatched photos with my first post the secondary baffles are beside the V&H baffle. In the other photo it shows them fitted.(i still had to fit the heat shields)
