how to do true duals on a 95?

how can i true dual my tahoe? it has the 02 sensor right in the why pipe where i cant cut it to weld new pipe on. do i have to change to the earlier manifolds or can i move the 02 sensor up some? will that hurt anything? thanks!

Just remove the stock system completely from the manifolds, run new 2.25" or whatever pipe size you want and weld in a new O2 bung. Done. The closer the O2 is to the engine the better as it will be hotter.

It is also fine to leave it basically where it is location wise but only have it in 1 of your dual pipes instead of the y, mine was like that for years.
