These mufflers are hand built and polished in the UK with a USA supplier at hand for parts,etc.. Listed on their website as: PR1828 for $150. I bought the headpipe separately from the UK too. It uses the exact same exhaust seal as the OEM Vespa system.
Requires specific fasteners/spacers which I will include.
I am a professional mechanic-> questions are welcome.
Fits nicely to this scooter and hard to find a high end system for this price.
Weight of muffler alone = 4.23 lbs. The pipe might weigh barely one lb?
I want $150 complete & well packed, plus actual cost shipping to your location.
Save my hearing.
