[@abesin203]

Is this the gp1rs or v3mini 140mm specially designed for zx4r/rr?

[@Pierre-Irwan]

Neither, as far as I know AR don't make for zx4r. This one is a shorty pipe 51mm inlet for universal motorbike.

[@duck8280]

sounds like a full exhaust on the 4R?

[@Pierre-Irwan]

It does! but it's a slip on. Full exhaust on 25R.

[@MohammedNameerAnsari]
