Sound clip with gutted cats?
Does anyone have a sound clip with gutted primary cats and stock resonator/mufflers?
A week or so after building my midpipe ('06 GS300 AWD), I'm getting a p0430 (cat efficiency below threshold bank 2) code. From my understanding, some have had to add o2 extenders when the rear cats are deleted... some dont.
In this case.. I'm considering gutting the primary cats and running extenders to keep the CEL off... however I don't want the car to sound ricey/raspy as it's the wife's daily driver. Not spending 1200+ per side for new oem manifolds... and don't want to spend $1200 on ppe headers. The car is getting 25mpg mixed driving conditions... so I strongly doubt there is an issue with the primary cats.. so I may end up just running extenders.. but would like to see what the other option sounds like..
Anyways.. does anyone have a sound clip with the primary and secondary cats gone with stock exhaust otherwise?

I had test pipes on, but I was forced to take them off due to a loud exhaust ticket. It sounded like a v8 stang on x-pipes, anyways I put the stock back on to pass the noise compliance test and barely stayed at the 94 db mark for a v8. The thing is I left my o2 spacers on with the stock cats and its throwing a p0136 & p0156. I deleted it with my obd2 scanner, but sooner or later it'll pop up again thinking I don't have o2 sensors on. My dilemma is Idk if I should put back my megan test pipes or remove the o2 spacers & forget the test pipes? Man I wish I didn't live in cali, I get smogged every 2 years and don't wanna end up stripping the 14mm bolts removing the cats on and off.
As for the OP, I have a sound clip somewhere on youtube with megan tps, deleted resonators on mid pipe, attached to hks axle back. Drone is loud in cabin but idk man, I don't wanna go through the hassle of cops pulling me from loud exaust, put the stock back on, get tested for db noise test, then pay fix it fine to court. Maybe I should sell the test pipes & o2 spacers with it?
