@Vitpilen401Rider I’ve replaced the stock cat with the LeoVince’s cat-delete in addition to the Akra already on my bike. Sound wise, It’s loud enough. Radically changes the sound of the bike especially at full load. I’ve kept the baffle otherwise It’d be too much ( for me and for the other road users ). No error but IMO It’d probably need a remap and an air-filter. I’ve probably lost some low-end torque in the process but the top-end is much stronger ( hence the remap & air-filter )
Good thing with the LeoVince’s is that It has a backbox so for the untrained eyes ( for the police ), It look as if It was stock.
