Hi all ,
I have gone through the thread in older forum but am not able to find it here ..
Does anybody have the information on how I can dampen the loudness ?
Regards,
Pravin
keep the baffles packet correctly, and add some turndown tips at end . will help *some* take some of the bite out of the tone
Fixing the stinger helps too.

yup. slight turndowns cut it some. as above.
Not sure if it works but I remember reading a post someplace where the guy took a strip of sheet metal... the length of the inside of the silencer and at a width of the diameter of the perf core... gave in 1 twist so it was long cork screw, put it in and tack welded it in place. Apparently the exhaust pulses deflect off it and ere directed more into the packing without really restriction flow.

Without cutting the sections open there is no other way ? :umm:
The turn down I can understand is add a slim pipe section instead of the cylindrical last section and then add canister at the end right ?

lol I thought it was too good to be true
Turn down tips don't really do much either.
The TYGA shorty cans on my Garrett pipes have turn down tips and they are LOUD AF!
Strangely, the TYGA Classic cans on my TDR Martin77 pipes are just two inches longer, but WAAAY quieter.
What's up with that?

Actuall, after a second look, the tips really dont turn down much.
no you need a good curve to it. it def helps.
Whoever said size doesn't matter was lying! Ba Dum Tissss...
But look at suppressors on firearms. They work in a similar fashion. Short ones just don't have the volume to absorb and dampen loud noises like longer ones.
Soft foam ear plugs work for me.
Type of intake will affect the noise level as well. Pods make your bike a lot louder than an air box, or even a y boot.
I thought the DG pipes on my bike were quiet. They are made out of pretty thick steel which helps eliminate the ting ting sound a lot

I have to I guess first seal the exhaust flanges nicely so there is no trang frang smoke coming out and adding the noise
Then I will try the turn downs ..how about opening the end caps and adding some glass wool wraps ?
The baffles should absolutely be packed with muffler packing. if they aren't already, do that 1st. Might be all you need if they aren't.
The chambers on that TDR look so otherworldly organic. I'm almost disturbed by them. Very sci fi look...

I've been to Jim's place, and those pipes are really cool in person. The TDR is just a really neat bike altogether.

Martin has gotten really good at hydroforming over the years.
I believe he uses a pressure washer to pressurize the pipes with water at over 2000psi.
