87 S4 auto...
Hey all,,Well after starting a tranny filter change, WYAI bit me..so..after transmission springs new hoses/lines, exhaust hangers, cleaned painted exhaust, and undercarriage, new vac lines and modulator,and a cat bypass...on the road with a great sound...and no leaks!!!
But the bypass doesn't have a usable port for the O2 sensor..It has a dummy outlet..as it turned out my old sensors wasnt hooked up to start with.
So, what is the disadvantage of no sensor?
Also, the power seems to be less at lower rpm..seems a bit dogged....
thnx as always...
