Hi, I bought a pipe off of ebay and once i wire brushed the funk off of it it looks like the only markings on the pipe or silencer are the letters "PS" or maybe its a Square and an S im not sure but could you guys help me get an idea on who makes it? It looks like the Torquer pipe. It is a one piece design, i.e. the headpipe is not seperate like the stock one, it comes with a cylinder flange that uses no gasket, straight slip on.

 

well if it is one piece, i'd say an old DG.
but if it says ps maybe it is a PSI.
What chassis does it fit> The old school sport, trail boss.
