i am running a o.s.21 and i need some new exhaust. rite now it has a real skinny pipe on it and i dont think it is breathing and having the power it should be plus i dont know about dual chamber and whatever else. could someone give me a link to a good exhaust that they fell would give me the most power out of my engine and also tell me about dual chamber and that stuff??
thanks,
