    I've got akra slip on now without dB and it's quiet.
    You can tune the noise with the length of the pipe you use..
    I'm going to buy an elbow pipe off AliExpress..

    Update...
    I've ordered a 250mm length of stainless tube 54mm O.D that will fit snug into my akra slip on, for £11 on eBay.
    This will eliminate the internal perforations that deaden the sound and thus a slightly louder note..
    Basically I'm sleeving the bore of the akra can.👍

    I have a video on my thread of the breadbox removed only - cat and stock slip-on intact.  I really liked how it sounded.

    Yes, it's the breadbox that stops all the noise.
    I've just made the $8 exhaust slip on, and noise is perfect and bike feels crisper with very slight popping in decel

    So you are basically bypassing all the Akra baffles but not the look of the can 😁😁😁
