Hi,I have SLP tri-y headers at my engine and I consider would it be better place for o2 sensor if I replace it to collector?Now it measures oxygen only at cylinders 3 and 7.Propably need to go heated sensor if I replace it,but hopefully this modification gives better average values of oxygen.
How about other tri-y users,have you replace o2 sensor?

When I had my SLP Tri-Y headers I added another O2 bung down by the last collector on the other bank where it could pick up cylinders 2,4,6 and 8 but can't say I noticed any difference. Also it was a heated O2 sensor.

 

Ok,thanks for reply.
