I have a Blue Flame Oval S/S Dual Tip..... sounds great and with a K&N air filter I havent had any performance problems.... I would like to know, form those that have one, how it sounds/runs with both plugs out.... I havent had the time yet to get the right set of Pliers to remove the C Clip to remove the bottom plug.....
Just bought a Leo Vince and will hopefully be fitting it at the weekend so i'll let you know how it sounds and affect performance... Hopefully it'll sound lovely and not cause any problems in the performance department.
Just fited a Leo Vince SBK to my TT and its lovely. Hasnt seemed to affect the fueling and feels nice and smooth, it might actually be running a little rich, I'll have to see how fuel economy goes.
