Can't get above 65/70 at full throttle on the interstate.

I'm looking for an air intake tube, thinking it sucking too much air through all the holes in the folds of the old one. Maybe the catalytic converter is stopped up? If that's the case what can I do about the choked down cat?

Randall, for starters, grab some cheap duct tape and wrap the air intake tube to seal the holes until you can get a replacement. That probably won't fix your problem, but it will keep dirt and debris from entering your engine while also ruling out that this is the problem. to see if it is a plugged cat, you would have to drop the exhaust to see if it will run properly (or at least better) when disconnected.
