I have MBRP 4 inch with cat now. I am wondering how much my egts will come down with cat delete pipe. Also do aftermarket intakes lower egts much? I am running about 1330 degrees pulling 7000 lbs up steep grades on tow/econo setting now. Hits 1400 and backs off in the 90hp setting within a few seconds.

How fast are you going up those steep hills?
