More or Less Quiet Peashooters

I have about 3000 miles on my MK3 now. One side always sounded a bit funny at idle and it has never had the classic commando sound that I love.
Anyway I had a pair of old Toga Peashooters in the garage that were on one of my bikes about 20 years ago. They are in average shape. I remembered these sounding great and the only reason I removed them was kickstart was hitting and chrome was wearing. Anyway, today I put those Toga exhausts on and the bike sounds perfect, runs better and idles better.
Check this out: I looked into the 2 peashooters that I removed. See this image and you can see one of my "New" peashooters was not made correctly (I dont want to mention where i got them- they are not EMGO). They are in the image above the Toga- :

Thats too sad/funny. We may have rest of life tasks down pat but these Commandos can sure rub our inner egos to goo. If ya not too scared to follow into hobot smoothie camp consider beveling the 2 front cushions edges narrower some.
Btw I would not of paid attention to the flute shapes but a decade+ ago NOC fella did deep search for the missing sound of new silencers so checked my Combats decaying innards to find finger nail shaped flutes and locals saying they knew it was an eager Commando on the way. Only one I'd heard at the time so didn't know nothing.

Mine are AN with logo maybe two years old tops. The internals look like these with three rows of fingernails so to speak.
On both silencers near the clamp end a section of the fingernails are out of line with the others, jogged a bit to one
side so to speak.
Sorry I cannot seem to get a pix for you.
They are not especially quiet even though I put mutes in them. If you go easy on the throttle and revs you can be
respectable but if you give it a handful and some revs when passing someone they will get their windows shattered.
No crossover no doubt isnt helping.

I've arragned Z-plate spacers so it tipped them back inwards enough to clear kicker swing but fudging other things may still be required as no two Cdo's and replacement parts are ever the same. Its possible to get pipe swing clearance but then kicker fouls the foot peg stalk. Had this happen once out the blue trying to start for return trip and KS stuck down and would not release so pushed off and got in depressed mood to dig into tranny expectiing lay shaft bearing but KS released as I undid the foot stalk mount, which i could of done on the road if I'd looked closer. IIRC some early peashooters had a circular baffle plate with space aroun dit and a small-ish hole that caused a sort of whisling sound on let offs. You can buy or make these to experiment for fun.

On my '73 750, when she loses kick starter clearance. it is because the head pipe has shifted. Long ago, I too have spaced the mufflers' hanger brackets to the inside. If the head pipe is set as far to the inside as your swing will allow, then the front end of the mufflers are set to the inside too and that gets rid of the kick start lever clearance issue, at least for me.
Wes's '71 and my '72 both have the peashooters flair-ing outward some besides upward which when following gives the impression of a rider resting legs on them like a Star Wars jet scooter. Alas the angle of the dangle of the multitude of headers varies enough that what works for one may not another. I"ve been through like 4 header sets on two Cdo and each one took a bit different combo of fudging and forcing to stop the clang clang clang.
Hobot youhave posted pictures of one of your bikes in the past with a 2 into 1 exhaust. what brand is that ? of is it a one off and did it work well for you? Cj the reason I ask is that I'm trying to piece back together a 2 into 1 that came from a previous owner. I need to get the collector, Bwolfie hooked me up with a company called cone engineering that makes all sorts of exhaust components. when looking at CNW web site I saw that Matt had teamed up with Cone Egineering to make and supply him with the pea shooters that he offers. They look to be well made and might suit the original poster of this thread...however I'm trying to sort out this 2 into 1 that I already have in hand.hobot said:
The original thread is well over 3 1/2 years old, the OP must have mufflers of some sort by now.
The MK3 system with collets and rounded shaped washer/seals along with the flared bell shape header pipes allowed kind of a gimbal sort of an adjustment to the system to facilitate fitment of the balance pipe. I don't know who the maker is but I have seen this set-up on systems with out the balance pipe and the extra freedom of adjustment made them easy to install and adjust to prevent fouling the kick-start or anything else.

Shoot some our Commando are over 3.5 decades old and the lore still worth rehashing and making more.
cj Peel's -1 was scabbed up One Piece welded from its first factory dual pipes that got too ugly to keep. The rusted siliencers blew off on first trip out with locals. Funny learning curve why all off the shelf two into one's all have a Y union to take apart, the exhausts are splayed outward so Peels were trapped after welding till I figured out-forced them to spring apart enough to remove and install again. So lucked out but next set will have a union between headers. In Peel's small port Combat case once mega restriction removed Peel went form ordinary Combat power to wrist straining sports bike hunter. I made sure the collector pipe ran close to frame and clear of kicker. Next set I'll get a TIG to learn to DIY. Can't help on your store bought 2-1 but the principle can work a treat though make take fiddling lenghts and silencer openings and even cam degree to wake it up or pretty disappointing like Peels was till a few versions of megphone end short of wide open ear injuring cattle scaring farmer shooting loud. I will try Peel old 2-1-mega on Trixie come spring to see if works similar with dual Amals and large port Combat head.
This is with stupid heavy supertrap mulit plates adapted in place of Dunstall tube cluster and bean can covering them.
Final pressure relief solution that surprised the snot out of me when Peel about ran out from under me next time out d/t butt snagging on tail light mount before could let off.
