Which exhaust.. Beaudesert or Redback ?

[kevin07]

Sorry I'm against the lot of you. unless already done I'd be fitting boost and EGT gauage so I can monitor any changes a new exhaust will make.
Could be doing unseen harm without them , thats my 2cents worth. Then Chip and Zoorst at same time you'll notice a huge difference then

Not much change from $3k for zoorst and chip

im with threedogs as well fit the gauges first also probably wise to get a ultra gauge or scangauge pm my third for that one so if you get any codes just clear them

Had a Beaudesert exhaust put on my 2011 GU patrol in August, still smiliing, extra power/torque noticeable as well as improved fuel consumption. Beaudesert installation was fantastic even had to make a modification to the tail pipe due to ARB rear bar, nothing was too much trouble for the team. Highly recommend them.

Can't comment on the redback but the beaudesert is brilliant and was a huge improvement for low down torque. I needed bit more torque for towing as I was finding I would have to stretch 2nd gear to about 3500+ rpm so when I changed to 3rd I would be around 2000 rpm to pull the van. With the 2.75 beaudesert I change gears normally as the truck will pull the van from around 1600 rpm Huge improvement!!!

I heard these guys do a lot of R&D on their product. They found if you go 3" they had some over-boosting issues so they stuck with 2.75" , hi flow cat and muffler.

You'll find the Beaudesert ones are alluminized steel , high tech

Choice of aluminised steel or stainless steel.

do you mean they have two different models ?

[BearGUST]

Aluminiumised steel (ACMS) is nothing fancy, its just mild steel. I don't think you can buy any mild steel exhaust that isn't ACMS.
I've got the redback 3" on mine which I did before fitting a chip, huge difference! IMO on a forced induction car there is nothing more important than a free flowing exhaust.

Diesel is an oily fuel which means you always have an oily film in the exhaust which stops it rusting out. Stainless is overkill.

so I am wondering... if the exhaust made so much difference, why didn't Nissan themselves make the change themselves as in making it factory installed ?

[MEGOMONSTER]

Probably the noise and pollution restraints.


Jack taps here...........

Same reason engine crankcase gases are recirculated into the engines intake. Its all to keep the do gooders happy. All the restrictions placed on our motors in the last 20 years are for environmental benefits and regulations. The best thing for any motor is clean air in and exgaust air out as quick as possible to allow for more clean air in and with better flow the engine can run so much better.

Thats correct. got quoted two weeks ago for the two different systems. only different is material. (and price...)
