Stock Exhaust sizing S430
Previous owner cut the cats and resonators off of the car before I bought it, trying to find the size pipe to replace the cats with (not putting cats back on, personal choice not up for debate). What size is the pipe leading up to the first cat from the headers? Also leaving the cats going to the resonators? Attached are pics of what I see if the pipe from the engine bay, cut right behind the O2 sensors. *2000 S430*
