I just finished fitting a DEA 3" exhaust to my 08 patrol with cat sounds good had a hard time removing the old one.(that's what took most of the time) every thing fitted fine except one bracket near the auto gear box.
Took it for a drive it is a lot more responsive no turbo lag now.

Got a 3" Genie SS on my 2009 and love it. Sounds soo sweet and noticed it even pull a bit harder. Have had no issues with it at all.

Thought I'd add something to this. As my car's been at the mechanic and dyno over the last week or so, while I was there I bumped into a bloke with a 2013 CRD cab, manual.
He had endless issues with turbo spiking and limp mode with a 3" exhaust, and in the end the shop where he got it done, dropped it down to a 2.75, and hasn't had a problem since...
This bloke is older and isn't too technically involved under the hood, so he had no clue about dawes valves and such at the time. This could have ironed out his problems quickly. It just seems to me that some CRD's are too sensitive to 3" than others, on some it works perfectly and others not so. The dyno guy showed me a few charts of factory CRD's, and the default boost control is absolutely S***! It is just a mess of zigzagging lines all over the place... Adding a exhaust just multiplies the problem without some boost control.

exactly 10 in a row are good with 3" the next couple are no good there then comes your way a pain in the freckle

That's right, it's hard to believe that such small difference in exhaust size can make a difference in how the ECU responds.

I have a 2.75 Beaudesert pipe, and a wastegate actuator system setup.
