87 350 Y-Pipe

[Italianwagon]

Question for y'all. Gonna have a new y-pipe built/installed. Have the y portion I want installed and pipes built around them. Any worry about messing up the o2 sensor or function of the tbi with different y-pipe? Thanks

Dep3bds on the O2 sensor and its location. If it's a 1 wire and you locate it too far back it won't get hot enough. Other than that NBD. If it's 1 wire Is switch it to 3 wire anyway.
