here are some of the dyno charts, from the bikes that were tuned by customers from the UK, and europe.
A GSXR 1300 Hayabusa
blue is standard, red is my bolt on mufflers, and then the green is the complet works, akropovic system headers and 1 pipe.
SIDEKICK MADE 11.3 HP FROM A SIMPLE EXCHANGE OF PIPES
SAME BIKE , TORQUE CURVES


Suzuki 1200 bandit..

i had a call from the dyno tester, we have done some major engine work on a bandit, now would be the time to get your pipe on to test, ..

so the first stock run was done 116 BHP
after the engine work was done, and prior to the final tweaks of the carbs etc,  about 4 months later, I went and we fitted my pipe, and as you can see it made a massive 22bhp over stock, (not normally this much due to the rebore etc) then as the customer had decided on a "well known brand" as many people do !! the final run was dne, the bike was set up to this full race system and silencer and ONLY managed to gain 19bhp over stock..

as you can see my pipes were non optimised, so they were simply just bolted on with no enhancements to the already race system
ANOTHER OF THE HAYABUSA CURVES

Here another person with "A WELL KNOWN BRAND" Blue is stock. red is Yoshimura and Green is sidekick, , sidekick made 7.4 hp , bike was a GSXR 750

this was a pipe tested against BSM in Sweden, for a magazine

VTR 1000 FIRESTORM, roll on 4th gear, sidekick 7 bhp over stock
Through the gears, notice how both increase massively over the flat spot in mid range, found on every bike, and thats what a decent race can should get rid of..

FIREBLADE OVER 8BHP OVER STOCK
DO I NEED TO GO ON...

THESE PIPES HAVE BEEN TESTED, BOTH NATIONALLY AND INTERNATIONALLY, THEY HAVE BEEN PROVEN ON QUALITY AND PERFORMANCE AND HAVE BEEN FEATURED IN MAGAZINES AROUND THE GLOBE..

AND ARE ALL HAND MADE INDIVIDUALLY
