my mates got a liquid cooled aerox and the exhaust has 2 pipes comin from it... 1 is the ristrictor which we have removed... but what is the other 1... and should we remove it? i looks like it has somethin to do with the coolant system?? cos it conects to a rubber pipe?!?!?! cheers
its the air recirculatory system. it basicly p[ulls air from the tranny case and adds it to the exhaust to lower the emmissions. its part of the cat basicly so can be removed. no need to block the rubber pipe.
