Ragazzi ho trovato sto tipo ammerigano che produce sti due cosi da martellare all'inteno dei termilani dopo aver rimosso la paratia.
L'idea sembra furba perchè sono dotati di filetto interno dove avvitare un tappo, certo però che 100$ è tanto per fare una prova
Le foto le ho recuperate da Instagram e dice di aver montato il tutto sulla sua Iron 2014
Istruzioni:
The Loud Pack Plug is for sportster/iron owners who have the removed the baffle plugs from their sportster/iron and found out how nasty it sounds or are looking for a better sound without spending $$$ on pipes.
To install you must remove the factory round, flat, plugs, that are welded inside the exhaust pipes. Then you hammer in the Plug, we recommend using a 12" long, rod of metal or wood to help with driving the plug about 6 inches into the exhaust. There's no whistling noise at all with the loud pack plug installed!
Repeat process for other pipe and enjoy the new, deep, perfectly loud, exhaust sound for your bike
The Loud pack plug is tapered to better direct exhaust gasses through the muffler packing and the hole is threaded in case you wanted to go back to OEM sound by simply screwing in the included bolt
