Look forward to your report! Are you getting an EGT guage as part of that setup?
What's the diameter increase over standard for the exhaust?

No EGT but exhaust is ceramic coated. 3" dump pipes. Rest of exhaust is also coated. I think that should really help with EGT temps. If you look at their site they list Legendex exhaust for D3/4 (made by Genie just round corner). There s not one on shelf for RRS so mine will be modified D3/4 unit. However they reckon once mine is done, they will have template and can do others easier. I have to wait for exhausts to come back from treatment.

I had this done to my L322 (at Roo) and very happy with result!

Just had a look at the Roo's Website and there doesn't seem to be any information about what they can do for a RRS. Can you advise what increases in performance you are expecting??? And sorry this may be a silly question but has your exhaust failed, is that why you are replacing it or purely for better performance??? Would also be good to know approximate costs of this, I am looking at doing some long term caravan hauling and would be keen to know what can be achieved.

Meccles you have a 3.0 SDV6?

FYI here is the Roo Systems Dyno map on a MY12 SDV8 (4.4 dual, sequential turbos) pre and post 3 inch dual exhaust and ECU remap "Towing and Touring".

That's a rather impressive increase in power and not too shabby for torque either.

Indeed Graeme, quite noticeable...and sounds sensational too as Grant will attest to Quiet when cruising along at a set speed...and a beautiful V8 growl when you, err, flatten it...
