AB is correct here.......This is the most common place for a pyro however, not all dump pipes come with the boss for the pyro probe & if theirs not one present then you'll need to weld or have one welded in place.
I would strongly advise against trying to drill & tape directly into the dump pipe itself.
The Autometer pyro includes a ceramic washer and steel hose clamp setup to allow the probe to be drilled into the dump pipe without the need for a bung. 1/4" (6mm) hole is all that was needed when I installed mine this way, and I can't detect any exhaust leakage around the probe.
I've seen this setup & yeah, they seal up the pyro probe but given what a 4WD does I personally wouldn't risk creating a weak point in the dump pipe & the possibility of cracking one when out bush.
A boss in the pipe would prevent this from happening.
Just my opinion though.
The ones I'm eyeing off are the autometer ones. So you guys say they come with a part so nothing needs welding just a drilled hole? I'm thinking I can handle that hahaha.
If it's timber I can do it, mechanics and I'm in strife lol
came scross these 2 instruction PFD files for the autometer gauges

unless i get it professionally done i cant do the weld.
for my skill level im thinking the clamping method i was to do it myself.

Yeah I agree with patch here. For what its worth, I just got an exhaust shop to weld and plug the probe. I did the rest. Cost me no more then $50. ZD's have an annoying heat shield that can be a pain in the ar** to remove.
I guess it comes down to personal pref on this one. (mine is an autometer too.)

Yep, the first manual is the one that comes with the box and what I used.
All you need to do is drill the hole mate and put the plug in with the ceramic washer and hose clamp.
This is only my opinion....It's fine, works 100%, I have never seen or heard of one cracking and "IF" it did happen then It's only the dump pipe and you can always get home, just a more beefy sounding car on the way back thats all...LMAO
whats involved in getting to the dump pipe?
yes you may be laughing, but im serious lol
i know nothing about mechanics. I know how to drive and learn hahaha
Just wondering what we need to pull of/move to get to it.
cheers
I'm not sure about your set up but I would imagine it is impossible to drill anything whilst the dump pipe is installed.
You will have to take it off unfortunately and put it in a vice to drill, weld or whatever you decide to do. Won't be the funnest job in the world and you may need to sacrifice a spanner to get access....lol
You could maybe jump under the car and see if you can get access from underneath but I doubt it.
