Would this keep a pinto quiet?

After buying a long branch manifold that I cannot get to fit, I don't want to buy something else that I cant use, does anyone with a bike can on
a car engine think this would do the job.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Doesn't the material used make a difference to the exhaust note? I thought Alloy cans tended to me noisy compared to stainless.....

it does say not mot legal which says to me its too loud for the road and in such will be too loud for the track too.. you need a can which is
repackable.. big is good - the bike ones are very small.. length and diameter..

I had a pair of race bike cans on my Alfa V6 engine but they were too loud so I swapped them for a pair of standard R1 cans which don't sound
any quieter!!
Bike cans need to be stamped with BSAU 192 or something, to make them MoTable. The noise they make isn't measured for MoT but it can be measured
at the roadside by the plod.
The only way to find out how loud your car will be with the can on is to fit it and see or find someone who already has the same set-up. Standard cans
don't usually have removable/repackable innards but race cans do.

Hi Mark,
I can't comment on a Bandit race can / Pinto combination as I have never tried it, but I can give you a couple of snippets on info.
In my experience the length of a race type silencer has more effect on sound reduction than the diameter.
Long & thin is better than short & fat, but obviously long & fat is better still.
The inlet on many super bike cans is often quite big.
It's my belief that on a bike, the pipe from the collector to the can is used as an expansion chamber, hence the large diameter.
My Thunderace (same as an R1) was over 60mm.
Standard cans are another thing altogether.
When I loaned Jonbeedle a T/ace standard can (with modded inlet) for his SVA it gave a dB reading of 87 on his cross flow.

I put a Micron race can frm a zx9 on my crossflow at one time, it was so loud it hurt my ears and couldnt drive more than a couple of miles without
earplugs.
