Chamber Delete from Competition Werkes for 2020, 2021 401

By this you mean the competition works chamber delete?

I personally decided that it sounded / performed the best with the stock muffler.

Ya, so you tried the chamber delete with stock muffler and you liked it better stock? Hey that’s good. Spending less money is always in favor!

Did Vintage V ever install the chamber delete?
 
LoL... I never managed to install the delete... I have all the exhaust parts in the corner of the garage but became distracted with other projects! Also I'm really happy with how my bike runs and I've been hesitant to make changes that will likely effect that.

Hey vintage v, if you wanna get rid of that chamber delete, I’ll take it off your hands. Lemme know.
 
I have the Akropovic exhaust with the Db killer removed, it took a lot of work and patience with a Dremel tool, but I was able to remove that rivet in there. Anyhow, it's still not that loud. I've thought about this, but I'm worried it'll be too loud. Do you know how many decibels louder the bike was with that flow through pipe? Also, did you feel you got any horsepower gains? I also put on the Coober foam airbox top, that also helps if you haven't done it yet.

Thanks,
E
 
Completed the Competition Werkes (CW) Chamber Delete on my Svartpilen 401 this past weekend.

It is a moderate level modification as you need to remove the entire exhaust system (header, muffler chamber and canister) as well as the skid plates which Husky calls a spoiler.

NOTE: I have the Akrapovic slip-on exhaust mod. It looks great, sounds ok but I wanted more sound.

I’m not a mechanic by any means, but have completed many moderate level modifications on motorcycles and Jeeps.

The instructions are minimal from CW, but as expected for an aftermarket purchase. Also, this is a newer part so no YouTube videos to use either. So, as a novice mechanic I supplemented information with the Husky Svartpilen 401 user manual. Also, that way, you have the torque settings after reassembly.

The most challenging part was the final step to remove the actual muffler chamber. The bolt “tube” was flush with the frame mounts so I had to slightly bend the frame mount, pop the muffler chamber with a hammer and…

Say NO to muff chambers

When reassembling, make sure to keep the entire exhaust system “loose” until you get the exhaust system and the skid plates reassembled…then tighten everything. I had to readjust as the header pipe as it was fighting with the skid plates.

NOTE: The smoke is the WD-40 ”seasoning“ the new CW pipe

UPDATE: I have since updated the exhaust to a Coffman‘s Exhaust Shorty. Posting is on the forum. I could NOT be happier!
How much louder was the exhaust with the chamber delete? Did you take any dB readings before and after? I too have the Akrapovic exhaust, but I removed the dB killer. At idle and 3 feet away it's at 93 dB. I still would like it to sound a little raspier and a few more decibels louder, maybe 100 dBs at most. Would this give me what I want? Also, did you notice any power gains by simply removing the chamber? Thanks!
