You should be able to look up the test info to see how you are doing. Some riders have also added a turn down on the pipe to bounce the sound off of the ground first to help dampen some of the noise. The exhaust sound from a big 4 stroke will also carry farther than a 2 smoker for example.
I am sure my SuperTrapp is not the quietest pipe option, but I keep the packing fresh and have played with the disks and found the compromise between quiet and performance I can live with. Like to know how that app works.
That's essentially what I'm trying to do. I want decent performance, but not overly loud. The factory insert, even after modifying it a little was very restrictive. I'm happy with the performance of it without the insert, but it's a bit loud. I have a friend of mine welding up a turn-down for it right now which should help a little, but if I need it quieter than that I'll make a custom insert (like the old re-packable Thumper Racing inserts).

If I had an extra $300 I'd throw down for an FMF Q4, but I don't have the money. When I got the bike it had a god-awful loud old Supertrapp IDS that fell apart in multiple pieces when I tried to repack it. Picked up the 600R muffler for $30 shipped to replace it.

I would try to have a muffler shop make you a pointed down tip like the xrsonly one back in the day...

I did this for my stock klr650 muffler which was stainless btw...so I tig welded a stainless 2 1/4inch tip...it quited down beleive it or not and flowed better...not only that but my headers stopped glowing! jajjaja

I have used standard type loctite with success. It is basically doing the same as what it does for threads.
Great for worn splines etc... fills all the gaps and stops any movement. It is the movement which causes the wear.
Also I find the metal surfaces seem to be protected from rust. JFYI
And Christian.... doing fine tnx same back

It would be pretty easy for me to fab up an insert like this one that Thumper Racing used to make.



For now I'll try just the turndown. If it's still too loud for my taste, I'll stick a re-packable baffle onto it like in the picture.

^^That's cool! I've tried to picture a turn down for the SuperTrapp, but it would be like hanging a mailbox off the pipe.

did some work on the XR today,

Filled up with oil, kicked it over so the oilpump would move out the air.
set the valve lashes (0.15mm/0.20mm Hotcam..)
Mounted the FCR, with some swearing and cutting the adapter I need... :)
Fiddled with mounting the airbox so it wouldnt hit or barely hit the shock (single carb airbox/twincarb frame)
removed a piece of fender bracket under the rear fender which didnt support anything.

and tried on a CRF silencer to see if it would look good..





And of course one of my friends felt the need to set it on fire.



anddddddddddddddd
*drums*

Put the worlds most badass valvecaps on the wheels...

Nothing ceremonial. friends and me included just want to set fire to everything they see. The 'hairs' on a new tire? Most of them are gone..

box in which I carried my engine to a friends shop?
gone..



XR engine not co-operating?


dynoing a drz? flame it!



and much more..

Found the carby venthoses!!11!!1!!! yeah!!

Did swap a few with the original XR carby hoses, FCR's were too short on 2 or 3 spots.
Mounted the header, need to take it off once to put some heatwrap near the carb, its sitting a bit close. to the accelerator pump housing..
Cut a new piece of fuel hose, the FCR sits a bit farther away from the fueltap compared to the original dual carbs, note that the fueltap has a 6mm outlet and the FCR has a 8mm inlet.. needed some eh.. 'help' from mister lighter and some lube to slide it over.

pics inbound, will try and fire it up after dinner. Mom wanted me to come over so I have to leave the garage for once

some random pics, as seen, the twin/single carb swap is tight.

royal kudos on the good work

Id be interested in a few things you are doing

1. a pic of the heat shield wrap you plan on using and how you did it, or what wrap you end up using.
2. Im interested in knowing what adapters you made used for the intake boot and or airbox boot in order to fit the quite big fcr.

lastly are you planning on dynoing the bike? do you have one near you? Id love to see what you end up with...

or maybe just an a/f measurement?

thanks

good work!
