When fitting an Akrapovic exhaust do you need to change any sensors or modify anything else.

Does it make much difference. Can't decide on malossi variator or Akrapovic
Both is Also an option longer term.

Depends if you are chasing a higher top speed or faster acceleration. My GTS250i has a 12 x 140 rear tyre, a Mallosi variator and is currently running with 15g rollers. The result is slightly slower acceleration but the revs are much lower for a given speed. BUT, I daren't run it flat out as the belt will rub on the casing and in time the heat will destroy the sump gasket leading to oil leaking into the belt and roller....not good. Had this happen twice now and also had the belt snap twice due to the rubbing. When I get round to it the variator is going to get changed back to standard but with some Dr Pulley sliders instead of rollers.
So, bigger rear tyre and the exhaust would be my advice and keep the drive train standard. If you REALLY want to pursue the Malossi variator you could try using a Malossi belt which I believe is thinner so that it doesn't rub. However, I understand that they only last a couple of thousand miles and a VERY expensive. |
