One of the Toga brand mufflers on my ‘66 A65 was looking pretty tired. The chrome had lost the shine. I can’t bitch about it too much, since I bought them used and they have been been on the bike at least 10 or 15 years. MAP is advertising A65 mufflers on eBay for $230 a pair. I ordered them and they turned out to be Emgos. Normally I am not a big fan of Emgo parts, but these were dimensionally right on the money, the chrome looks great and they sound fabulous. Peering in side, they are straight through with a perforated tube. We will see how well they hold up, but at this point, they appear to be high quality at a bargain price!

Ed, tell me again, do the Emgos sound like the Togas? Because I heard they were obnoxiously loud. I remember hearing Togas on an A65 once and I thought they sounded good. If the Emgos sound like that, I may consider a pair.

I have Armours now. I've had them since around 1988. I've always felt that they're too quiet (and possibly too restrictive), and now they're starting to show their age.

Mark,
They sound great to me. I don’t think they are too loud. They don’t have that tinny sound some aftermarket mufflers do.

I prefer the Brituro silencers not much more but a sweet note and perform well too, the emgos are a touch louder but sound good (I have a set of triumph ones)
The armours ones are much quieter and neighbour friendly in that sense, but knock the power back and kill throttle response which was why I ditched them (they’re also fatter and with stock brackets fouled the kick start)

Get the emgos (I’m thinking the emgos are the same as the Wassell branded ones?? Apologies if I’m wrong) if you want the sound dimming down, sleeve the tail pipe. Biggest problem is the pipe used on the tail section is the same as the sleeve pipe on the inlet, knocking back some midrange power and increasing noise. If your fortunate enough to find an original you’ll see the outlet pipe is the same OD as the down pipe. So some 1.5” pipe with 1.5mm wall and some 1 3/8 pipe with same wall thickness will slide in the tail, improve the exhaust note and thicken up the midrange.

Bought a pair of Emgos for the road T100. They fit and look good but don't sound the same as the ones that I got with the bike. The ones that came on the bike were one straight through and one with baffles along with non matching pipes so I assumed the bike had had a spill and one side was replaced at some time. No complaints and about the same price as above.

Cheers, Wilf

Ed...I put straight-thru Emgos on the Tbolt when the originals finally got bad enough to annoy me. They do seem a little louder than the originals (which had baffles). Only complaint I have is you can see the weld point circumference unlike the originals.

I have the emgos on my 68 A65 and so far they have been on for 4k miles they are too loud for me so I put 'slip in' baffles and that toned them down a bit

Only company that could possibly be would be armours, and if they by chance were they aren’t made to the original specs, otherwise I’d suspect you’d been fed porkies there.

From some of the other replies, it sounds like there are Emgos with baffles and those without. Do yours have baffles?

I have a set for mine (although running a Dunstall mega at the moment) they are excellent, just wish they would make a clubmans silencer.

When I lived in Birmingham in the early 80's and wanted pipes and silencers I went to a small company between Aston University campus and Bracebridge St, they did all the pipes and exhausts for all the UK makes, never asked them if they made the originals but it was likely they did. Their name escapes me and the site is long gone and student accommodation now.

Brituro went into voluntary liquidation in Nov 2018, so buy up any stock now.

Mark,........ You may be recalling my "too Barky" post. They look good, fit, and mine now have the "can opener" baffles in them. Even so, still not the sound I would like to have, but I'm not embaressed by them anymore. I can bring the bike home without being obnoxious. Just my $.02.

Mark,
No baffles. Straight through with a perforated tube. I imagine if I cut it open, I would find that the tube is wrapped with steel wool or fiberglass.

Ed, the perforated tube IS a baffle, no? I mean, I've seen mufflers that were nothing more than a hollow shell!

I agree with Allan, it's probably not wrapped, especially if the baffle (perforated tube) is not removable. I have a pair of Rocky "trumpets" with removable baffles. They were originally wrapped, or packed, but the packing deteriorated and started coming out so I removed it. Point is, the mufflers didn't sound much different with the packing removed. Now with the baffles removed, Good God it was loud! ...and the engine wouldn't rev.

All told, I think I may give the Emgos a try.

The emgo 'dunstal' copies are good, easy to remove centre tube and add glass wool to taste. I tend to like them quite quiet thesedays.
A little attention to the bracket/fixing method makes things a little better, single sliding bolt attachment is a bit lightweight.
Put a large bolt/blank in the centre baffle tube from the inside to give them a little more restriction, helps with the 'go' especially with linked headers.
The short emgo meggas are crap in my opinion, but very popular.

Mark,
A baffle would be a plate or plates, or something similar, that redirects or impedes the exhaust impulse. I do not consider a straight through perforated tube to be a baffle.

Same here, they are absorption type silencers, you can see through them but the perforated tube takes the edge off the flow, absorbs it into the outer chamber and then adds it back into the flow taking the edge off the pulse.

You might not, but no disrespect when I say it wouldn’t make a good argument. you could always read a book on exhaust tuning. But what Mark says is very much correct.

One of the biggest problems with glass packing is that it eventually blows itself out of the tail pipe. Whilst it adds some noise reduction it isn’t much. And as previously mentioned you get more problem because of the size of the outlet pipe on the exhaust. Ever see a boy racer with a massive tail pipe making a [***] load of noise but not a great deal of “go”. This is what most exhaust silencers are. A louvered baffle will only worsen performance more, a straight baffle tube is the better option.

To save repeating myself....

I don't remember who sold me the silencers on my A65, but it was one of the UK based suppliers (Classic Bike Shop, Fecked, etc.) they are good quality and sound great.

The baffles are the corregated type which run around the inside wall and seem to help form a nice deep rasping sound not too loud and fairly free flowing.

I have no idea if these are Wassel, EMGO or other but they work well.

Alan,
I do not disagree with what you are saying about tuning. I disagree with the term "baffle" for an absorption tube. It is simply a matter of semantics. Kommando has it right. A "baffle" is generally defined as a device used to restrain the flow of a fluid, gas, or loose material or to prevent the spreading of sound or light in a particular direction. Plates or other similar devices normally "restrain" the exhaust gases in an effort to reduce noise. Absorption tubes on the other hand, may alter the sound but do little if anything to "restrain" the sound. I am speaking generally here of course. Under the tuning theory you mention, I suppose one could argue that having a less than ideal pipe diameter would "restrain" the exhaust gases, making a "baffle" out of the pipe itself!

The packing i use is the gear a load of japper scrambles type bikes use, it's a very dense glass matting , stays in the pipe and makes a massive difference to noise.
If i fill the meggas with it , it's quieter than my car, i just use about a 1 inch thick lining. Same gear as the classic racing club boys are forced to use at many circuits now.

I remember back in the uk, the coppers would pull us up and stick a metal rod up the exhaust, if it didn't hit a baffle you were nicked.
