Excellent so far mate. A slight drinking problem, but by no means excessive. After years of small capacity engines where high revs are required, it'a a pleasure to get max torque from 1200 RPM

Hi Robert, mate got his done 12 months ago. Made a big difference to power and fuel. Can nearly keep up with my 4.2 . Mine was better on fuel than 3.0l on trip to cape york which was surprising. Price sounds about right. Drummo

On this matter of stanless steel.

How long do you think you will keep this truck?

Also think about the servicability of stanless V mild steel.

Stanless is more suceptable to fracture due to work hardening from vibration & movement.

AND

Any half skilled monkey with an oxy torch or a standard MIG can weld up a mild steel exhaust.
Stanless...a well now.

So do you recon that stanless is worth it.

cheers

As a Boilermaker since the 70's I've welded plenty of Stainless and Stainless exhausts cracking is only an issue if the exhausts are fused without adding filler wire.
As for serviceability, in an emergency it can still be welded with mild steel filler it's just that the weld in that area will rust, no big deal.
Most of the big exhaust manufacturers use 410 grade Stainless which actually looks similar to Aluminised Steel tubing and as a Ferritic grade it is also Magnetic.
I have a Pacemaker Stainless system on my Diesel Pajero and it's fine.

so do you recon that the stanless system was worth the extra $200 to 300 over the cost of the same system in Aluminiumised steel.

Bantam, I have no issue with people using whatever material that is safe to use.
If people want to pay the premium then that's fine by me, I chose this course myself.
Fortunately I am in the position of welding and understanding these materials and I have no qualms about using the Stainless system supplied by Pacemaker.
If I had wanted to I could have built a fully Tig welded system out of 304 or 316 Stainless but there's no way I could have done it for the price I got the Pacemaker system for.
Regards Andrew.

Most definitely, it transformed mine. Better low down torque, more usable power, better hill climber.

15l/100 towing a van to Canberra, not too bad I reckon.

Only time I have really measured it

Hi Robert,
I recently purchased a 2011 patrol, it has a 3" Manta exhaust system and their Sting performance chip. It totally transforms the car - much better response and performance. And gives a very nice exhaust note :-) compared to my friends standard 3.0l patrol
my economy was 12.5l/100km driving to work and home each day.
I just blocked the EGR and the turbo spools even lower in the revs now and gets to and hold max boost much earlier (monitoring turbo gauge).
fuel economy looks like its improved - but wont know for sure until I refill mid this week. I was getting to 320km at half way on the fuel gauge, this time I didnt reach 1/2 way until 380km...

Bryan..
