Do you guys doing anything special with the o2 sensors?
I've got some bypass pipes on the way (might already be at the shop)
Have an HPDE this weekend -- so I don't have too much fiddling time.
If they just bolt up I'm golden and might give it a go.
The drone at 2-3K was BAD! with just the Borla muffler.
I do have smog to deal with -- but I could always swap back if I need to pass and can't as is
