A quiet exhaust, especially suitable for original cylinders but offering significantly more power in the middle and upper rpms. Supplied in a black heat proof paint with a chrome heat plate.
E-marked (legal for road use)
If you want this pipe derestricted you can purchase a 'derestriction' from the spare parts tab

The 2nd pipe from the exhaust is related to emissions and does not help performance. It is not needed on mopeds for an MOT so all the aftermarket exhaust suppliers leave them off - most people just block the end off then tuck them up out of the way on the bike although it isn't necessary to block the pipe.
If you derestrict the exhaust it's important to fit a larger main jet, usually a 10% increase in the main jet size (larger then the standard size fitted) is adequate so long as it still has the standard air filter and airbox.
