Dolmar 421 vs 420?
Worth porting a new saw?

I'm thinking the only difference between the 420 & 421 is a cat muffler. Are they worth porting? IMHO I think the 420 is one of the best running 42cc saws out of the box and porting would only make it better. I had one an it blew 195psi and was bone stock......Great little pro grade saws...
