I have the Triumph off road pipes on the bike, are the Thunderbike pipes going to do a better job?



I have the 2005 SM with Thunderbike pipes.
According to the figures provided on another thread by Graeme Lawson of Thunderbikes (RCV on here)the pipes will only give you a 4 hp boost in performance on the 865cc engine - the boost on the 790cc engine is considerably more. The TB sound is pretty good though.

I think I read somewhere that the Triumph off-road pipes give you more than just 4 hp (I repeat, on the 865cc engine).
