ThotYouKnew

It's been awhile sense I have been back on this board due to spending the last 4 years in college and hardly driving my 96 Z. I am throwing code P0420 which deals with the left side cat/ 02 sensor. I am thinking of removing the cat and welding in a dynomax bullet muffler. I would still be running a cat on the passenger side. Does anyone have experience with this? Would I be messing up some sort of balance of pressure with only having one cat installed. Also, if this set up does work, anyone know the part number of the correct Bullet to buy? I am running on the stock manifolds. The only upgrade is my LoudMouth which obviously is attached beyond the cats.

Any help would be greatly appreciated. I am currently getting ~15 or 16 miles to the gallon and I am guessing that it has something to do with this code.
