Was fighting an oil problem and probably burn 2.5 qt of oil in less than 300miles. All because of a stucked close PCV valve. Is my new less than 1000 miles catalytic convertor toasted? I notice the car pops a long more at deceleration than before the oil problem started. 3 inch donwpipe, 3 inch pipings, 3 inch cat and 3 inch straight thru muffler.

Car pull 20inch of vaccum and boost fine. At least I don't have to inspect it for another 2 years.

I would'nt think so. My exhaust is the same and mine 'pops' quiet a bit too always has

My parent always know when I'm close to home from the poping on the long hill in front of our house:thumb:
