Anyone able to tell me what a mechanical muffler comprises of? Iv got an msc micron. Which I was told had the mechanical type muffler. On this very forum I had read they can restrict performance so thought I would try it with a standard repackable can.

While it was off I decided to look art the inside so took the can apart and all that is in there is a baffle with a spring holding it in place, no wadding or anything. Is the spring part what makes it mechanical? Or have I just got a weird can that's missing it's waddling?

No pics sorry it's too dark out now

Iv been illuminated by someone on square tails.


I didn't know what the craic with the spring was. Once it is packed with wadding I don't see what it does cos the baffle will be pretty solid. Seems it's just a standard silencer and not the mechanical type

the old mechanical muffler was not repackable.

when you unbolted it from the main body and removed it - it had a perforated pipe that went into the main body

the later repackable type is a can with an end piece held in by a large circlip - when you remove the circlip you withdraw the end piece which had a perforated pipe with a spring welded on the end. - the perforated pipe does not go in the body of the exhaust on the later ones

the spring is to put the pipe and wadding under a bit of compression when you push the assembly back together so it gives a bit of resistance.

If you omit the spring there will be little/no compression ofthe assembly - it may seem tight now but in a very short space of time the endpiece and perforated tube will start to spin - which is firstly annoying due to the noise and secondly derimental to the tail pipe as the wears the ends away resulting in the circlip groove been smoothed off - result been you need to adapt the end

this is from experience on both micron and taffspeed pipes which are the same idea

Cheers lad. The spring is loose on this one. Could have snapped off at the end at some stage though. Iv been running it without wadding for a while as that was how I got it, I had heard they were loud so thought nout of it. Still is mind, it's not as raspy now. Much lower tone though. Which is far better

MSC micron wow
A mate on here had one on his T5 years ago using the standard mechanical muffler , it was one of my old tuned barrels and upjetted carb but my god it flew BUT the only problem was because the can was so heavy it use to break the rubber cotton rubbers !!!!!
He latter had a TS1 and after trying different pipes he tried a micron and worked really well BUT again the muffler was way to heavy so opted for the ally stinger type (as above) and sounded sweet and worked great! I think a mate has put it on his tuned lam 200 stage 4 and again works a treat !!!
Really good pipes and quiet hard to come by nowadays

sorry to hijack but when you say 'tuned barrel' how do you mean? 152 kit etc or work done to standard top end?

Standard top end but tuned !!!!!
jacked up barrel ( I think it was 1.5 mm) head skimmed to suit and work to the exhaust and the tranfers fettled...
I use to have it on my T5 but passed it on to sooooosh onn here as I had another one done, I ran a cut crank fettled inlet and a mk1 mikeck
