Moto Guzzi V100 Mandello - 4 different exhaust setups in 66 seconds

Swapping my exhaust components, thought worth a short video. The limitations of the phone camera mean volume difference is not as noticeable, but once you take the catalytic converter out this engine barks like a real Italian stallion. My stock pipe has had its diffuser plate cut out so is a little more free flowing than a total stock one. The stock setup is beefy enough at idle, but really homogenises the pulses at higher revs for more of a fizz, I don't really like it. The headers change the character completely, and raise the volume substantially. Aftermarket setup is also much lighter, and puts off a lot less heat than the cat does. The performance with aftermarket setup and the UpMap tune really makes it feel much more responsive with less lag on the throttle and removes the recognised flat spot in the stock fueling.
