Hi, I just got home from a weekend away. Had intentions of camping out but the weather forced me into other arrangements but we got some 4wding done and that was great.

I had my 2 adult sons with me and a reasonable load of camping gear and the EGT kept running close to and sometimes over 600degs.

Had to back off the go pedal several times after the alarms went off at 600degs.

I was wondering what I can do to lower the temps. I have been considering the Beaudesert 2.75in exhaust for a while. How much, if any, will that lower the temps. I was driving at 110kph doing 2700revs and EGT was sitting around 500degs.

2008 GU ST 3.0ltr diesel 5spd manual.
Thanks for any advice.
Paul
