[triprop]

I wanted to put a new exhaust on my x-pro storm 125 because the stock pipe runs below the frame. the description shows a 28mm OD but the one i got is 25mm. plus it has a wonderful (sarcasm) weld inside the mouth that further reduces the ID. I bought a 150cc 3 speed engine (for fun) and the last thing i need is a smaller exhaust. They better waive the restock fee and return shipping. will let you know what happens. first time ordering with them.
