yes they are long enough, mine has 6 bungs i think for a wideband or whatever u desire...

 

they should have 6 bungs on the OBX. Your o2's will fit fine, but the rears need to be turned off and you will need 2 plugs

 

I've heard you can plug them with 2 spark plugs.

 

Make sure you plug the 2 extra bung holes.

 

I'd put the rear O2 sensors in and plug em in so it looks all legal-like

 

to plug the rear holes you need to go to autozone and buy 2 toyota oil drain plugs.

 

Toyota has 2 different size drain plugs, make sure you get the bigger of the two if you go that route.

 

Hey everybody.The installed is pretty cool but sometimes painass from the fitting issues! So far all OBX are up bolts on. And the y pipe with fake cats are on. So last one the lightning muffler with passenger side have problem the fitting to connect the y pipe. It not straight right. So all I need to take to SHOP this week let them do cut few inch off and re-welding. So I able have all muffler back on correct with level. But the sounds pretty good. I run with Hooker Amechamber. But I could tell from stock cats compare with fake cats the smell totally different! The fake cats smell like racing. I suppose to change thing the smell? I just wonder the fake cats will kill mpg?? That what I am consider for. Many thanks. P.S. soon post all pictures on this thread.

 

You just have to deal with the smell. After 6 or so months I was fed up with it and went with cats. No noticeable loss in power and no more fumes.

 

The smell will go away when you get your catback hooked up. It'll direct the exhaust out from under the truck. Also once you get it retuned you'll feel the performance difference along with see better mileage.
