ok so ive been going thu the forums to see whats best for my vz sv6(190) and you all recomend the 2.1/4 from the cats back.
isnt the stock exhaust 2.1/4?
so whats the diff?

With aftermarket you get a system that flows better.

 

[az_sv6]

how so? is it the way the pipes flow? and does it depend on the guy fitting it?

 

[Philthy]

Its more the mufflers that flow better than stock
