Hey all,
Does anyone know offhand if the stock catalytic converters are bolt-on bits? I'm guessing so, since all of the replacements have the flanges, but I want to make sure before I order them. I know that I can find out by crawling underneath and looking, but the car is at the shop getting ignition coils replaced.
Also, have any of you guys had experience with Pacesetter or Evan Fischer cats? I'm seeing mostly good reviews, with a few not-so-good reviews.
Thanks!
