I went with the Beaudesert for towing reasons and couldn't be happier. The increase in torque down low is amazing. You wont be disapointed. I can't comment on other brands as never had any others.
I tow a 2.7T van and the Troll does it with ease.

Oh sorry going on old info I stand corrected.
I ordered a bluetooth OBDII reader to go along with the software on my android phone. It should be able to pull up all the info from the engine. The only bit missing would be EGT... Alltogether about $30.
I went 3" from turbo back but as I have heaps of hindsight, if this was around at the time I'd have it in my truck in a heart beat.
Great choice look forward to you thoughts
Another fan of Beaudesert. Recently replaced stock exhaust on my 05 4.2 with 3" system (and dump pipe). Packaged well for delivery, very easy to fit - 3hrs including removing old system - and effect noticeable straight away, sounds good too even with single muffler. Had one on my old turbo'd GQ 4.2 and was the first mod done this time around. From memory it was $950 delivered.
3inch Redback here....
From all the threads on exhausts it appears the 2.75" Beaudesert job is a perfect match for the Cr 3 ltr, as boost is better controlled by the ECU
As for the 3" it's perfect for the Di 3 ltr with a Dawes valve controlling your boost
