nice...im surprised that you did not get a CEL....did you use a O2 spacer?

Sounds amazing, where did you make the cut for the secondary cats?

I saw that the left side is bolted on and the right one is a much longer pipe that goes all the way to the primary cat, but can't remember if that was a bolt-on or welded.

Thanks for posting

BerBer63

O2 sensor is only in the primary cat.

Supafly

icic...for our cars we have 4 o2 sensors...2 in the primary and 2 in the secondary..

Uhm... You do mean film and shift at the same time, right??

Because, seriously, if you can't drive and shift, well, how do you breathe and eat?

Just kidding, just kidding...
Actually they're in front of and right behind the primary cats (well before the secondaries) so they can get a differential reading to make sure the cats are working properly. Cutting right behind the rear sensors is a great way to have a clear enviro-conscience and avoid CELs, but it's still plenty illegal in the eyes of the law (At least in California).
