THE FRIST THING YOU NOTICE IS HOW LOUD IT IS, IT IS PROBLEY THE LOUDEST PIPE I HAVE EVER HEARD. AFTER I GOT IT JETTED RIGHT ( THANKS TO CENTRALS TIPS) I TOOK IT OUT FOR A QUICK SPIN. THE OFF IDLE RESPONCE WAS A TAD BETTER, THE BOTTM PULLED ABOUT THE SAME. THE MID RANGE HAD QUITE BIT MORE HIT , IT MAD ME LIKE 3RD GEAR, NOT ALLWAYS OVER REVING 2ND. ON TOP IT GAIN A LITTLE TO BUT SEEMED TO REV OUT FORVER.

FOR MY OVER ALL RATEING I WOULD GIVE IT A 8 OUT OF TEN , I LOVED THE POWER CURVE ME, BUT THE NOISE IS LITTLE MUCH

wierd...never even heard of a scorpion

These guys make heaps of road bike pipes - I had one on my Fireblade years ago - I thought that they were good value for money and the sound was excellent too if you dont mind noise !
Is it round or oval and where did you get it from ?
