    That's interesting 8608. Did you keep the diesel cat?

    Would you hazard a guess at how much louder the Prado is from standard with the new exhaust?

    Apart from the cash, the main thing holding me back from doing any exhaust mods on the prado is that it gets used a lot as a family trip car both on and off the bitumen. Passenger comfort comes above a few percent of driver satisfaction...

    If your talking about the noise factor, well it really is not that intrusive if you go for a reputable system. The benefits far outweigh the cons(not that there is any). Just a nice note and at speed (100-110kms) you cant hear it all.
    We get 150kms more out of our duel tanks - Now thats COMFORTING to the pocket..........

    Re: D4D exhaust & chip

    i originally removed the rear muffler from my factory system. this made a noticable difference in the seat of the pants department. not sure on power or torque figures.
    this made it quite noisy obviously.

    i then replaced the factory system with a beaudesert system. the beuadesert systems include the diesel cats as standard. i opted for no rear muffler at all, as i didn't expect it to be any lounder, but with the increased diamter of the dump pipe and the system in general, it is louder. extremely loud under boost/hard acceleration, but with normal evryday driving, its bearable.

    i now have a steinbauer chip fitted, and noise levels are about the same, but the power and torque is crazy wicked. i normally have the steinbauer off unless we are towing, or loaded up. the extra power and acceleration is too much for me... to drive slow. i just can't help it. plus, it uses heaps more fuel when its on. (i had my chip custom mapped for me with higher output figures and totally disregarding fuel economy) according to the wife, as she drives it daily, the very next mod is upgrading brakes.

    Re: D4D exhaust & chip

    Thanks for the responses.

    Sounds like a Beaudesert or Taipan with muffler might be the go.

    Are there any issues with extra heat or reduced clearance between the road and the exhaust with these systems?

    Re: D4D exhaust & chip

    Not at all Mike.
    If anything it runs cooler because the hot exhaust gases are exiting a lot more efficiently.
    I opted for the ceramic coated dump pipe which reduces heat greatly.
    As far as ground clearance goes the beaudesert ex is tucked up quiet nicely.

    Cheers john

    Re: D4D exhaust & chip

    Well time has come to make the move. Next week I am having a Safari snorkel, steinbauer chip and 3" exhaust upgrade. I am a bit annoyed at steinbauer as i sent them an email a couple of weeks ago to get some more info on thc chip - still waiting for a response. The reports here from Black Diamond match up with what the installer is telling me. My only concern is the impact this is all going to have on Mr Toyota the next time i have to get a service (routine or otherwise).

    I drop the Prado off next tuesday and pick her up wednesday.I will keep y'all in the loop. What an awesome Christmas present for me and the Prado.

    cheers

    Where did you email them? I sent an email to Hi Tech Disel Injection regarding the chip and they sent me back a heap of info about ten to fifteen minutes later last week.

    Re: D4D exhaust & chip

    I sent my email on the 30/11/10. Did you get some good stuff? My email was to steinbauer direct not to Hi Tech though so i wonder if this has anything to do with it.

    Re: D4D exhaust & chip

    The job has been done! The snorkel looks the goods and there is no real increase in wind noise. The Steinbauer chip is in. Wow what a difference. A lot smoother, the auto gear box doesn’t hunt around as much or do a big jump from 5th to 3rd going up hills. Oh yeah there is plenty of get up and go under the right foot (almost forgot ha ha).

    The exhaust is the only real issue. It is bumping against the exhaust heat shield under the driver as well as hitting the cross member where it bends over the axle at the rear. The worst is the bumping on the exhaust heat shield as it appears to be at certain RPM and mostly as soon as you come to a complete stop (nothing under normal driving). This is probably more annoying to people in other cars (I just turn the radio up louder). It is booked in to be fixed in the New Year.

    Cheers

    Hi All, Has anyone tried removing what I think is the cat converter on the D4D exhaust. It is the first cone shaped gadget down from the dump pipe off the turbo.
    I have removed the big muffler and replaced it with a better flowing Redback muffler. I feel it made a bit of difference down low in taking off etc. I have a DP Chip fitted (4 years) great. I didn't find any extra noise with the muffler change and now wondering about changing the dump pipe down to first join. Has anyone had a go at it. I found the exhaust system on the D4D was pretty good and approx 2.5 inch +, so I didn't want to change it. Thanks and cheers Bill.

    Does anyone monitor their EGT's on the manifold upstream from the turbo exhaust inlet? What is the normal (low and highs) operating temps for a EGT monitor located in this area?

    Very useful thread with great info. I'm going to put a upgraded exhaust on asap and follow up with a snorkel soon after. I have the KD-FTV. Would you recommend the 2.75" or just go the full 3"?
