How far does the emissions probe need to be inserted into the tailpipe for the emissions test?
I have a dB killer in mine, which means the probe can only be inserted about 100mm into the exhaust tailipe. Will that be enough?

No, it will almost certainly vary from station to station as I don't think they all have identical equipment, but I would say you need to allow at least 10" of free entry space, preferably 12"
Ah, oops. Don't think the db killer is wedged in there pretty tight. Are these usually installed at the entrance to the silencer?
Think i'll need to get a replacement tail pipe and live without the db killer. Anyone know where I can get a 45deg tailpipe with a nice rolled
end for IVA?

dB killer needs to go in after the main silencer to allow room for gases to slow down & expand in the silencer, otherwise it's unlikely to be
effective. Can you not simply add a section of tube with suitable rolled end to the existing pipe to allow the probe to read gases - it only needs to
be there for IVA
Sadly there's no room in the Fury sill for what you suggest.
A 45 deg tail pipe is fitted directly into the silencer outlet, and it's in this tail pipe I've managed to get the DB killer stuck. At best,
I've got 7" of free exhaust length to insert the probe.
Looks like i'll need to get another tailpipe and run without the DB killer.

i initially put mine in on the tail pipe end, then had the same thought about the probe at IVA, so i swapped it to the manifold end, which made it even quieter, but it did screw my emissions and the engine didnt want to rev. Just squeezed through the emissions though!

Unfortunately I can't fit mine at the manifold end because the cat is in the way. Only option would be to put it inside the silencer, where it
may not be as effective. I think i'll chance it without it. Argh, it's never easy!

Fitting at the rear end of the silencer will be as effective as fitting in the tailpipe, but without strangling the engine, shouldn't affect
emissions much either, tho' could tweak them one way or the other

I left the decibel killer off until the noise test, the examiner was fine with that.
They got the probe about 10" past the sharply bent outlet.
Description
Not being able to insert the probe is likely to cause problems with the Lambda reading, same as even a very slight exhaust leak.
