I just ordered my edge today and it should be in my hands tommorow afternoon. I apologize in advance as I am sure this is not the first time this has been asked. To install the pyrometer, I would assume that it is mandatory to remove the exhaust manifold from the engine to drill and tap the hole. However, the guys at the shop I ordered it from say they drill the hole on the bottom of the manifold so that the shavings fall out of the manifold, then use a telescoping magnet to remove what doesn't fall out. My question is, A) has anybody installed the pyrometer while the exhaust manifold was still on the truck? and B) If so did you have any adverse effects from doing so? (i.e. metal shavings siezing the turbo) If it is necessary to remove the manifold, has anyone done this before and will I need a new gasket? BTW, truck is an 05 2500HD LLY D/A.

You've come to the right place. You DON'T have to remove the manifold. Go to the Do-it-yourself section and find the piece by Hoot on installing the probe. If you can't find it there then click on any of Hoot's notes with his signature. It is very straightforward. Drill a hole (generally horizontally, not vertically) as the pictures show. If you do it with the engine idling most of the bits will be blown out into your face, so wear goggles, and won't go through the turbo. Make sure you have the correct drills and taps and go slowly and you should be fine. I did mine and while I'm not all thumbs, I'm not all fingers, either.

Thanks a lot for the help man. I'll check that out now so I can be ready to tear into the box and start installing as soon as I get it tommorow.

When I drilled mine I magnitized the drill bit and all of the shaving stuck to it! Had the engine idling, worked great!

Have fun with the juice!

I recieved my ***/juice combo from JK last week and drilled and tapped my exhaust manifold using HOOT'S method. No problems at all I'm no mechanic (and I wouldn't make a pimple on a mechanics arse!). Follow the directions.

WEAR SAFETY GLASSES! I tend to cheat on this and can tell you the chips hit your face and eyes hard.

I use a "Unibit" step drill as they make a very nice hole, and the chips have a nice wide flute to evacuate through.

Even if you should accidently get a chip in the exh manifold, the turbine blades are Inconel which is hard, and the chip are thin cast iron which is very soft. It is unlikely to cause serious or even minor damage.

That's not to say it couldn't happen, but it's like if you pound a bearing out with a block of wood. Sure you could damage the bearing, but it is highly unlikely.

I'm having a local performance shop do the EGT probe install for $130. I mentioned hoot's method, he hadn't heard of doing it that way. He told me there is enough wiggle room there to loosen a couple of bolts, stick a rag in there, drill the hole/tap it, and install the probe. Make sense? JJ :)

When I did mine, to remove the inner wheel well, drill, tap, install probe, then to re-install the wheel well took between 30-45 minutes. $130 to install seem high. But he is removing ( somewhat ) the manifold. Is that just for the probe, or complete gauge install?
