Basically any online store has them. Advance Auto even sells BBK extensions ONLINE (NOT at the store though because it's really Parts America that sells them). Just click the closest sponser ad and place your order.
the only time you need o2 extentions is for lt headers. bc the o2 sensors are alot lower in the pipe.
That's not always true. Some midpipes put the holes too far back on the rears to get to them, and even then, some that will fit will just barely fit, and I'd rather have a little extra length. If the catted H is anything like the Prochamber, then it should just reach, you'll have to take the wire out of it's guide though. I really haven't seen what I'm talking about, just repeating what I've heard. I assume once you get down there you can figure out what they mean. I'll have O/R legs on my Prochamber so I'm hoping that the MIL eliminators will extend it far enough to comfortably reach.
