Hi everyone, I have just purchased a Honda cbr600f4 (1999), the last of the carby models. Anyway, it is a little sluggish low in the rev range so I figured I would by an after market pipe for it to increase the low down response and make the bike a little louder... I have been looking at the following makes and was wondering if anyone out there has had any experience with any of them: 1) Jardine RT-One Slip On - Full Race Baffle - Honda CBR600F4 ($260) 2) D&D Show and Go Slip-On Exhaust - Honda CBR600F4 ($306) 3) Barracuda Slip-On Exhaust - Honda CBR600F4 ($317) 4) Muzzys Slip-On Canister - Honda CBR600F4 ($283) All of these pipes are sourced from the US but the prices are in AUD. Any comments are welcome... Cheers.
