Default Magnaflow Catback question.

Hello guys, I will be changing my True Duals to a Cutom 3"or 3.5"? Y pipe merged to a 3-3.5 flowmaster merge and a Magnaflow cat-back.

Am I going to be restricting my Exhaust A LOT?

No, alteast not much. Last I remember the Magnaflow catback was damn near non restrictive.

I doubt it'll make any difference, since you're using that good merge. If you're concerned, grab yourself one of those cheap cutouts and put it after the merge.

FWIW I have dual cutouts after the header collectors and I freed up quite a bit of power with them uncapped, as opposed to going through my Magnaflow. I'd be willing to bet a single 3.5" cutouts after that nice merge will produce similar results.
