SO, i have a few questions. Im going to get long tube headers soon, and plan on having them done by a shop around town. My question is, am i going to have to buy the mil eliminators? or an oxygen sensor extender? Plus how long is the install usually?

 

Yes, you have to get MIL elims or a chip and extendtions. 5 hour install at my place and they are the best of the best.

 

If you're running a catted h-pipe then you won't NEED MILS. You can make O2 extensions yourself, you're literally just extended the wires. Mine took a whole 3 hours install time to do myself, including cool down time since I had just driven it.
