Im going to be installing L/T with a 3" collector. I plan on using the flow master y-pipe. The questions is, should i run a 4" pipe after the Y or can i just leave my 3" pipe alone. Just wondering if this will cause a restriction.

I didn't know flowmaster made a y pipe,are you talking about a flowmaster merge?do you have a 4 inch catback,what cat back do you have?if its a 3 inch catback there is no point to have a 3 inch into a 4 inch back to a 3,just seems like that would be a pain in the ***

That's what I meant. The flowmaster merge. I have the flowmaster cat back setup. But i also have a DMH 3" cutout.

Yeah that catback is a restriction,but with a cutout your fine,

Later i plan on changing that but when I drag race I'm going to use the cutout everytime. Thank bro
