How much difference does a 3inch system make over a 2.5 system ??



Is it worth going bigger ???

 

anybody ??



Jolly Green ???????

 

anybody at all ???!!!!

 

just using the cross section the 3" pipe is 44% larger, but it depends on if your 2.5" is a restriction or not.

Some say to change to a 3" at 330+, others say it is good for up to 350 before becoming restrictive
