ok... i think i am set on the hedman headers and y-pipe.... i know i need to fit these headers w/ some sort of sensor bung for the o2 sensor. what is the best way to do this? i saw this on summit, how exacty does this attach? or would it b easier just to have an exhaust shop cut a hole and weld one in? i dont wana spend a bunc of money to have welding done.

 

You bolt it onto the collector, and then attach the pipe you're going to fabricate to the adapter.

Or you have this http://store.summitracing.com/partde...rt=SUM%2DG2990 welded onto the collector (above the flange connection), drill out the pipe, and screw in the sensor.

Or, you get headers made for the job, like 68471's.

Or 2055's.

 

nah... i dont want to mess with all the air stuff. i think i will probably just do the weld in one
