Instead of drilling and welding in a bung for an O2 sensor prior to the muffler,(clients car) how accurate would a tailpipe extension tube with an O2 sensor be?

Im thinking of a 1 foot long tailpipe extension with the O2 sensor welded in as close to the muffler as possible, yet without touching the stock system.

I intend to clamp the pipe in place with a stainless sleeve clamp so its air tight.

Any thoughts?

Thanx Tim...I am really concerned about part load and WOT....I feel its still to lean based upon the plugs.

So, this is a drive and tune session with the LM1, allen wrench for the MPS (its custom) a POT for the CHT circuit and lots of chinese firedrills till I get the part load and WOT perfect...should be fun...not.

I actually may have a chance to buy a floor dyno that is being retired from a state inspection station...
I am hoping to get that with the computer and just acquire some simple dyno software instead of the inspection software...

That will make it a bit easier to deal with.
He may sell me the sniffer, but he may keep it...its up in the air and depends upon the state regs.
