I installed the EGT probe that goes with my evo race tonight and i noticed afterward that my truck sounds a lot louder....almost sounds like real loud injector clacking noise but it only started doing this right after the probe was put in...and the truck was stock tune the whole time. Anyone else have this happen to them? I should also add that there are no leaks around the probe

Considering this only happened after the probe was installed, i have no idea what else it could be!

What level are you race is set?

Try remoing the probe wire from against the firewall like it says to do in the manual i just laid mine across the top of the motor because i went crazy trying to figure out the same noise. Sounded just like an exhaust leak i tightened up every nut and bolt and clamp for a week or so before i moved the wire and thats all it was, sounds funny but its true...

Everything is still at stock settings...
