This with Borla muffler. Great system, and is all stainless. Best bang for your buck in my opinion.
If you plan on going with any type of forced induction, go to a 2.5 inch, but you will lose some torque that way. 2.25 inch is great for a NA Zetec.
Here is a vid of the Trubendz with a Magnaflow, I can't find a vid with Borla.
