I'm not sure because I"m a turbo guy but I'm pretty sure you need the pipe going to the cats because aren't they exhaust driven ports???

Ok is it a S4 or S5? Also you would notice because your car wouldn't pull very hard or fast past 4k rpm. My car ran 18 flat because the ports weren't opening.

Pack some bearing grease on the rods (S4), take her for a "spirited" drive. Come back home, pop the hood, check out the rods- did the grease get displaced?

I've heard of doing this, but I didn't have any grease, so I used a piece of string tied around the rod and watched if it moved.

You own a 7 and don't have any grease?
