I remimber talking to someone about a year ago about this and they said that they had done this with their 3.0 buildup. I can't remimber who it was but they were a toy mechanic.

I just want to know how to do this setup if at all possible with the O2 sensor and all. Any thoughts or suggestions?

 

guessing you want a true dual exhaust ?

 

You need a section of pipe that connects each exhaust pipe and place an O2 sensor in the center of it. Something like the H-pipes or X-pipes that the v8 crowd run on their muscle cars.

 

i ran duals from a Y-pipe from my muffler back. never had any problems and on the 3.0 it actually sounded great! flowmaster btw...

 

Yea I was thinking about true dual exhaust, not sure yet though. They way it looks under there you may as well just run one 2.5 and be done with it.

 

i have the downey setup with the headers and a y pipe to the single 2.5" all the way back and it sounds meannnnnn i love it.
