Prima Exhaust for 125cc – 150cc 2-Stroke Genuine Stella and Vespa ScootersCOMPATIBILITY: Genuine – Stella 125 2T, Stella 150 2TVespa – PX Series (VLX, VNX, VSX)New from Prima, for those who want the best! These are the nicest stainless steel expansion chambers we’ve seen! Thick material, exceptional build quality, perfect welds, and shiny polishing make this the pipe to have! With the same performance as a Scorpion, JL, or PM Tuning, but a MUCH lower price tag, this is the best deal around.Fits P/PX 125 and 150, with or without a cylinder kit. You’ll have to relocate your spare tire to mount it. A rear rack like the RRC5 will work nicely to hold your spare. Will also fit Sprint or other early models with a 125-150 engine, but the pipe interferes with the center stand so you’ll have to use a sidestand instead.Don’t forget you’ll need to rejet your carb!Looking for more performance upgrades? We also sell a high performance kit that includes this pipe!**NOTE: Does not fit Stella 4T.**NOT
