nice deal. by the look of those silencers, they are some old toomeys. u mind posting more pics of them (i.e. side, back angle) ?
and for 1500 u can get alot. i would get some new pipes, dune port, nosshead, carbs, pro flow air filter. maybe you could even fit some suspension in with that money if u find some good deals. as for pipes their are alot of good pipes for the dunes. rockets, toomeys, shearers, cpi's, etc, just depends on what type of power curve u want. also, i would worry about the engine first before the looks.
