Hey guys. I'm dropping a BBK OR xpipe onto my car in the next few days, and I want to know if I need o2 extensions. If I read correctly, some brands do, some don't. I don't have MIL elims because my Xcal II. It's a shorty header style pipe. So, do I need 'em, or am I good?

Thanks.

I always thought the o2 extensions were made for specifically 04's, and not sure if any specific brand would have different locations.

And on a totally random note, want does the 4R70W mean in your siggy?
