what i said earlier in this thread .........also a good reason not to use stainless on lammiesDiablo wrote: The problem will always be with Lambretta exhausts is that the engine is also the swinging arm and therefore the exhaust must be attached to it in its entirety and therefore absorb all its vibrations and movement
so i hope we can expect the SM exhaust from cam lam to be very good then for £750 plus vat !!!Diablo wrote:I'll be honest here and say I don't think theres any exhaust that consistantly fits first time every time or that doesn't have problems afterwards. This also includes btw the way the ones I think Muttley is talking about-nobody is perfect.
Customer service varies wildly.
Certainly deck and exhaust port heights vary on different machines which does have some effect on fit so often fettling is needed. Modular fitting to a range spreading over 30 years also doesn't help.
The problem will always be with Lambretta exhausts is that the engine is also the swinging arm and therefore the exhaust must be attached to it in its entirety and therefore absorb all its vibrations and movement. Some do this better than others. I have always wondered why all expansion manufactures didn't copy the Taffspeed system which IMHO is the most reliable expansion of all time.
I do get frustrated by the stubs also though and resent the fettling needed so they flow properly.
It could be argued that these pipe are made to a price though. A hand made pipe costs a lot more. Also in motorcycle terms they are peanuts-you don't get a can for that much.
It is right to expect quality though but you have to balance that against cost and one size fits all manufacturing.
