Exhaust - full systems v standard .

[ALEXG]

I bought my 1200GS with an unbaffled Remus Revolution can . Liked the sound (can't really call it noise) and the throttle response. Rode a mate's bike with the full BOS system . Liked the top end rush . Put my standard can back on yesterday and was surprised that my arse dyno said more low down grunt than either the Remus can or the Bos full system. I am toying with the idea of Remus headers but would like to see a chart comparing standard with full Remus and with full Bos (Akro's are just too ugly) . I am not interested in a system that makes top end gains only at the expense of low down tug . Can anyone point me in the right direction to find these dyno comparisons ?

HI,

I suspect that the top end rush is making it feel like its lacking at the bottom end.... My last bike an SP1 had loads of grunt, I fitted a full system and it then felt like it had lost loads of bottom end.... even though it was clearly making lots more power and torque all the way through the rev range, peak power was 135bhp against 121bhp and torque was up between 8-17lb ft all the way through the rev range, a few of my mates have had similar problems too. I've just fitted a full BOS system and it pulls cleaner and harder than the STD system. It seems to be a side product of having a new found top end.

Of course this is only my opinion and other people may think otherwise
