I bought an Aprilia titanium exhaust to replace the standard dustbin exhaust. I wanted lighter (tick in the box) and I wanted louder but I understand from the seller that it is very loud, measured at 105dbA on a track day! That sounds too much & likely to attract unwanted attention from the law. It has a "track day" baffle fitted but that doesn't make much difference. However there is a soundproofing cartridge available as a spare part on the Aprilia Spare parts web site. I have two questions, does any one have any experience of repacking this type of exhaust. If so how should the job be tackled?:devious
