Could someone please tell me the inlet pipe size for my muffler? I drive a b5a4 facelift 98 2.8L 2WD. I recently started working at BORLA exhaust, and I'm pretty sure I get a radical discount. I just don't own a lift at home, and don't want to look like an idiot not knowing my pipe size. Thanks guys.

 

The Borla systems are 2.25 inches, not positive what stock is. It is some sort of metric measurement, around 2 inches.
