Hi all, just got myself a low mileage uk2000 99. Really happy with it except for the noise from the exhaust (more my wife) At the moment there is a japspeed 4.5" cat back system and i was looking to put on a hayward and scott 3" back box. Does any one know if this will fit easily to the japspeed middle section? or will i need to replace this too?

thanks in advance

 

aftermarket exhaust could be 2 1/2 or 3 inch. you need to check which one you have first. Usually theres a flange joint by rear wheel
