I need some help finding exhaust tips.  I am replacing the exhaust system on my '71 and considering 3" and 2 1/2" aluminized steal systems.  I want my Vette to look stock on the outside and I am having a hard time finding stock looking & fitting exhaust tips.  Any suggestions on where to find them?  Once again, thanks for your help!

Back pressure? We don't need no stinkin' back pressure.  We have tuned headers, mandrel-bent pipes, high flow mufflers, chambered exhaust systems, etc. all with an interest of reducing obstruction to flow. Why then do we need "backpressure"? I would believe that the exhaust pipes not be too large for a given engine so as to not unnecessarily decrease the exhaust flow velocity and not to create backpressure. An engine is going to run without back pressure. That is, as long as we are not creating an excessively lean fuel situation that would possibly cause burned valves.
