The reason I was thinking 2 1/2" is also so I can use factory tips. Would there be an advantage to a 3" system when its restricted to 2 1/2" at the end? Kev
I have factory style stainless tips on 2 1/2" tailpipes freeflowing exhaust restrictions are not a concern..3" for big blocks,not when your small block is putting out what most big blocks do or better...to each his own..
