I bet you would be as stunned as I was to learn that a standard GP exhaust can out perform every other exhaust system tested up to 5000rpm !
yes I know that using bold is a bit like shouting but this was a complete revelation to me
I don't know about you but I am thoroughly fed up with my noisy 42mm Clubman exhaust and I have been seriously regreting fitting it for some time now
. Sure I get good performance but the noise is so bad that when I ride through villages people turn round and glower at me as I ride past. Old ladies pick up their dogs and back into peoples gardens ......

I picked up a standard exhaust at the beginning of the year fully intending to test it against the Clubman at some point but never got around to it. I think now I'll make some time to swap them over and see the results.
