What's the best exhaust?

[nikki2484]

I have a 2.8lt Turbo diesel MU and am wondering if anyone has suggestions as to which way to go with the exhaust.. Any help would be greatly appreciated.Thanks.

2.5 inch is the best compromise of cost and performance. 3 inch will perfom a tiny bit better but at twice the price its hardly worth it. Even a 2.5 inch is not worth doing untill the old exhaust is past it unless you are a power junky

thanks for the tip.. i like a bit of power to back me up but nothin drastic.. well i was quoted $500 aus to get a 3inch put all the way through and was just wondering whether it was worth the extra.. thanks again.

your exhausts are cheaper than is NZ Also remember that mandrle bends are better than pressed but in 3 inch it might not make much difference

i was quoted $440 for 2.5in press bent from back of turbo to exhaust. currumbin gold coast QLD.

Hi - i just went through this just the other week i got quoted 600 for a mandrel bent turbo back 2.5" system and nearly fell off my chair its not the cheapest thing.
So all i did was cut the old muffler out and repalced it with a hot dog.
It cost $170 installed and now it flies, the turbo kicks in earlier, better on fuel, plus it sounds nice but not horrifyingly loud.
Best $170 i spent on my truck

thanks, might check into that, does anyone have any reason this isn't as good an option as thr 3inch upgrade? please let me know, Thanks.

For the 2.8l I think that the 2.5 will produce more torque than a 3" unless you are going to run super high boost.

Mine makes some damn nice power and torque with the 2.5"

Don't bother changing the exhaust unless you are going to do the dump pipe. It is the most restrictive part of the whole setup. I did my exhaust and was not impressed. Then did my dump pipe and was amazed. Expect to pay 600-800 for a 2.5" Mandrel with Dump pipe.
