Tunit diesel performance chip with Redback 2.5" Hi-Flow exhaust system fitted

[knakkers]

Hey guys,
Im looking at getting a Tunit diesel performance chip with Redback 2.5" Hi-Flow exhaust system fitted to my 2002 GU111 3.0TD.
Went to Daalder Exhaust in Dandenong today for a quote & info.
They recommended to not go for a 3" exhaust & stick with 2.5". Reason being the 2.5" gives more low down torque for off-road & better fuel economy.

Specs of improvement with chip set on #5 only are
Standard 119Kw, with Tunit chip 145Kw

Standard 380Nm, with Tunit chip 420Nm


And i was told by Daalder exhaust that both Kw & Nm would improve even more by an extra 5-10% with the Redback 2.5" exhaust system fitted

Has anybody fitted either the Tunit chip or Redback 2.5" Hi-Flow exhaust to a GU 3.0TD??
Any feedback please

Hey mate, are you going to be at the 4x4 meet up at Neerum creek?

I would like to put one of our modules on your car the meetup if you are going to be there

I have talked with the guy who designed that 2.5" Redback system and he is adamant that it is the best system for a ZD30 (whether DI or CRD), for the reasons you mention - better mid-range torque, and improved fuel economy. He went through a lot of steel of various diameters to arrive at the 2.5 as best.

I plan to swap my 3" Scotts Rods system for the Redback 2.5", and will be doing same day dyno runs on both when I do. It won't be for quite a few weeks yet though.

How much does it cost to just install the Redback 2.5" ?

[knakkers]

I was quoted $1250 fitted

Got a better deal tho, getting fitted with exhaust & chip at same time & paying cash

will fitting the exhaust void my Nissan warranty ?

[Squalo]

No, Nissan isn't too fussed about exhaust systems.

Chips could be a different story, but I am yet to see evidence of a warranty claim being knocked back due to the presence of a chip.

Having said that, I think it's wise to play on the safe side, and remove the wiring and chip for dealer servicing.

thanx guys, who in Brissy is the expert on installing the Redback ?

[Squalo]

A1 Exhausts at Caboolture if that's not too far out of your way - I can personally vouch for those guys. Otherwise there are half a dozen A1 stores across Brissy. Maybe call the Caboolture store and ask which store they recommend - not all franchises are created equal :)

Is the Redback Exhaust better or the Beaudesert Exhaust better ?

Which one has more following on this forum ?

[satyx]

i have heard redback are currently releasing, or have realeased a new range of exhausts and are aiming at the likes of beaudesert and taipan XP. I think thats great as more competition can only be good for us in the long run. Havent met anyone with a redback installed yet, and i havent head many bad things about BD pipes so it would be hard to say which is best atm.
