4" exhaust - EGT gauge

[jberylec]

Does anyone know of a 4" turbo-back exhaust system I can buy that has a pre-drilled hole for the EGT probe? Or does that install pre-turbo?

TIA

you want to install your EGT probe on your manifold not the exhaust.....

[jblagg]

yea you wanna install the probe preturbo. Of you had a post turbo than your turbo will be getting hotter than the reading you get on your guage

Damn. I was hoping for an easier way.

Thanks :-)

It's really not that difficult. People make it out to be more than it is. Just drill the right size hole (21/64) for the tap (1/8" NPT) and get the tap started straight. It's even easy to get to.

If you wanted to tap your downpipe, you really need to weld a bung on the pipe because it's not thick enough to tap. Also your temp readings would be about 200 degrees lower post turbo vs pre turbo (manifold).

Tapping the manifold is really easy. You dont even need to unbolt anything, just crawl under the drivers side look straight up and there is the exhaust manifold.
