LTH racing exhaust "Midrange" for Vespa PV, V50, PK
The middle between LTH Road and Race exhausts. The midrange delivers nearly as much horsepower as the Race without the disadvantage of the big weakness at low revs. This makes it perfect for kart track racing and using a powerful smallframe on the road.
