I fitted my LeoVince road/race exhaust a while ago and i'm well chuffed with it but was wondering where to go next. It pops a bit when letting off and goind down through the gears etc, and was wondering if its worth getting the power commander / BMC filter (JHS) and what it'll actually do. Is it just "plug and play". Also saw advert for TRE screaming, "if you have a fuel injected Suzuki you need this!" WHY???
Thanks
