Pardon the pun.
We have the nagging P0420 code that is still giving us a headache. During my research I did find that it might be possible for a bad exhaust system to trip this code--as the O2 sensor does need a slight amount of back pressure to give a correct reading.
Now our resonator is shot. the back of the 'can' is rotted out and while it's in one piece and not falling off the car? It leaks like a bunch of drunks at a beer taste testing contest.
Loud and basically it has to be replaced. I'm kinda hopeful that fixing this huge exhaust issue might clear up the P0420 code.
Checked into a few replacements, most appear to require the old school 'clamp' method that slips over the pipes. Is that going to work with using the stock muffler and converter? I have no desire to sink another $300++ into a replacement muffler (the muffler is actually in fantastic shape).
Any recommendations would be helpful.
