				I have a ph1 172. I have just bought a ketc super sport stealth exhaust with miltek decat pipe for a 182 and a 182 exhaust manifold. Problem... I have two lambda sensors ATM but the new exhaust only has the single lambda sensor on the manifold.
will it make a difference if I don't put the second one in. Or should I drill a hole in the decat and weld a nut in to then put the lambda sensor in?
thanks
