So I've emailed the seller in regards to the Header + Catback kit, asking the diameter of the pipe because it wasn't listed in the item details. I'm curious if it's 2.5" or 3" or what have you. This is what I got:

Dear chromizone,

We are sorry it is the aftermarket product and we don't know the exact dimension.

Useful huh? They couldn't crack one open and see? Ask one of their previous buyers? call China and say "Hey! How big is that pipe?"

Oh the joys of eBay
