| Simple question is the evo system worth the extra cash over the slip on? |

I'm amazed you found an EVO system I fitted a harris system and the bike is Def making more power than the collector I had fitted Hard to explain but I can feel it that's for sure ------------- Forza Aprilia Racing www.forzaapriliaracing.co.uk |

I was to slow to get the cracking deal on the evo system! So she is fitted with the Austin Racing slip-on. I don't know what folks are going on about them being crazy loud! I went out with it on with the standard 50mm baffle inserts as it comes from Austin Racing and I think it is a bit to quiet! Mind out I used to ride my gen 1 RSV with a Harris high level slip-on! So it's a baffles out ride for me and if a bit loud maybe put the shorter 50mm baffle back in and give it a go but I doubt it!!

| Don`t forget, you will probably need to get you ECU reflashed to race spec, no need to buy a RACE ecu, some official Aprilia dealers are able to reflash to the same spec for less that half the price |
