So true. I na nutshell an engine is an air pump. You wouldn't try to run air in and out of it with 20 metres of 1 inch pipe each side.Quote:

Hehe, Told the missus I hit a truck tyre carcass on the freeway and ripped my zorst out, then told her that a new OEM pipe was $1400 and I could get a new one, if I fit it myself, for 9hunge :) She thought I was soo smart in my findings. God I'm good.Quote:

I'm not sure how a s/s pipe sounds better than a steel pipe? Thought most people use s/s for looks and anti corrosion properties
I did consider putting a chip in. However the no. of chips available is quite large and I haven't done enough research to know which is a good one and which shop does it best.
The second issue is that my troll being a new one warranty is an issue. I called up the local dealer and the service manager said that if there is an issue it would be onto me to prove that the mod did not cause the issue. He was a bit hesistant with chips however with the exhaust he said that it generally helped the engine.
With the chip, I will have to get something that is removable, so I can take it off before service and even then I am not sure the service people will be able to detect the changes. However I am open to all ideas about it.
so that the reason for my pref for exhaust, its relatively simple and generally dosent cause any issues and Nissan are more tolerant about it.
I am with Threedogs & Nishead,do gauges first, a 3" exhaust will cause the turbo to spool quicker & can cause it to spike or overboost, if the exhaust guys knows his sh1t then they will know this, this is not good or generally healthy for the 3l, fit the gauges first & foremost, know what is happening all the time, dont let a 3k mod turn into a 10k mod, I spoke with the Redback rep on the weekend & he told me it is better to fit a 2.5-2.75" system, no spiking issues, they will sell you a 3" but prefer you to know what might happen, others dont & they know but it is nothing to do with them so often you are not warned. For me that is a major issue, I dont keep a spare 7k plus sitting around waiting for it to be spent cos I didnt think ahead, do the gauges, exhaust & chip, then dyno it & adjust the boost issue accordingly, learn to understand the gauge, this is the only advise I can give, I dont like to hear about 7K oil leaks in the driveway with big lumps of metal in it
I'd agree that 3" is probably overkill too, I got it because the price was very right... (I got chip and exhaust for $1000)
The redback system is only 2.5" from the turbo outlet into the cat anyway. I assume other systems are the same as the 3 bolt flange doesn't really allow for anything bigger.
On the Noise thing "in the old days" yes, every one used 2" copper pipe, sounded better ,fumes would kill you, but sounded better
Can I ask why you want to do all these mods to a brand new 4x4 in warranty?? very curious
Haha, I'm tipping same reason everyone else does mods. That's pretty much the reason forums like this exist.Quote:

Mate read a few threads about warranty and Nissan wouldn't be your choice, No such thing as a 4x4 salesman he only crunches number.
You the buyer know more about the 4x4 than him, thats why you pay $xxx to drive a 4x4 and he drives a sedan.
Can meet you any time go to any dealership ask a few questions and 10 out of 10 times salesman wont know the answer
