I found someone that will replace my Catalytic Convertors with a High-Flow Magnaflow one. My question is which Magnaflow model would you recommend? Some look standard and others are "spun" and a different shape. What is the inlet and outlet? Magnaflow says that my exhaust is 2.25" so I would think I'd want that but I thought I heard people saying it was 2".Standard:http://www.car-sound.com/02pro...1.asph ... spMetallic Cat:http://www.car-sound.com/02pro...9.aspSmall Displacement:http://www.car-sound.com/02pro...0.aspEtc.

i wouldn't bother unless your old one is pooped out. they only free up like 2 horses or so.

If you do go with a high flow, the exhaust is 2".

A horse is a horse, of course of course! I'm looking at all I can get and they're relatively cheap. The cat and the labor I'm looking at about $100. Mine is also one of the first cats they used and since that TSB I don't feel very confident in it and I think I'm starting to hear something rattling in it.

What's the difference between a 2-way, 3-way, and 3-way + air catalytic converter?Nevermind. I wikipedia'd it. I'm so stupy.
