Default EGR and headers?

Do the TOG headers have a provision for the EGR valve or is a blockoff required? If you can't reinstall the EGR, how can you pass emissions testing?

Yes the TOG have a factory connection for your EGR.
It'* your choice if you wish to block it off or not.

If you block off the EGR valve, don't you run the risk of burning a piston? Like the '92 EGR-less engines did?

I don't believe that.
It'* not the same engine really. A few changes since 92.
I haven't had any problems like that with any other vehicles I've had...and I've removed the EGR'* on.
Sure keeps the intake tract a lot cleaner & cooler when it'* blocked.

Okay, just checking. I didn't want to mis-inform anyone.

You certainly want a 180 thermostat and a fan override as a bare minimum. EGR'* decrease combuistion temps. Make it up somewhere else if you delete it.

Don't forget that the egr never comes on at WOT too. Plus it adds better gas milage.

The EGR valve, or the EGR block?

The EGR valve gives you better milage, and doesn't turn on at WOT.

Allmachtige and i burned the late night oil just on this subject. Really the only reason most people do it is for keeping an intercooler core clean. It will keep the upper end clean as well, but you won't notice a benefit in the butt dyno.

Yes, this is true.
I lose about 1 mpg with it blocked, don't believe it is doing any harm, don't think it improves performance too much (it must lower the intake temp a little cause the exhaust gases are 500*+F) and it keeps the intake tract and TB licky clean.
Sure the combustion temps must lower a hair cause the intake charge is being diluted with sooty exhaust gas instead of heat...and power...produced by air/fuel mix. It is added after the MAF sensor.
The whole idea is too re-burn a little fuel rich sooty exhaust gas that hasn't combusted fully, for emmissions purposes.
