Japspeed 4-2-1 manifold

[ReedHill]

My back box has rusted off so it's time for a full upgrade been looking at manifolds, the japspeed 4-2-1 it's one of the cheaper options but is it any good? I put ones on my bosses pulsar gtir and it kept cracking anybody have any experience with the japspeed manifold? Also is there a better option that isn't a fortune?

Cheers

Plenty on here seem to have run this manifold without issue. For the price you won't get anything better.

Its the facking great melon catcher that looks about the same diameter as a bin. I had one on mine, it was loud as hell with an unsilenced b pipe.

Not fused about the noise I just prefer the look of the donkey dick style tip
