Hey guys I just swapped in a 95 HO motor into my 01 xj, my stock manifold does not cover the exhaust ports. I wanted to use a 95 header and weld in a pipe from the header where the flange is down to the main cat and muffler. What would i need to do with the 02 sensors to make sure it properly runs. I know the 95 cherokee has 2 o2 sensors while the 01 has 4.

 

Hope you have the ECM from the 95 model and what else I do not know......but the good news is that a few here do know what you need and will chime in shortly hopefully.
