    Default Free Flow, wat dink die mense?

    Middag Mooi Mense

    Ek oorweeg dit om `n Freeflow op my 2.4 Hardbody te sit. Blykbaar effens meer krag maar ligter oppie juice.

    My vraag is 2 voudig.
    1. Hoe werk `n freeflow?
    2. En is dit die moeitewerd?

    Dankie

    Yes it is worth it.

    There is no sence in fitting a "free flow" and the bends are restricted. If you go bigger on the diameter pipe, then the bends are your restriction. Unless you use mandrell bends.

    PS. None of the regular xhaust shops use mandrell bends.

    PSS. A decent free flow xhaust is an art. Very few people have the patience to do it right.

    Hi

    And what about a free flow on a diesel car,does it do the same as on a petrol car?
    Performance wise ?

    thank you

    Definitief die moeite werd. Shop maar rond en kyk ook na stainless steel as jy die voertuig nog vir 'n ruk gaan ry. Ek't het nou onlangs 'n 63mm op my Patrol hesit, en dit werk goed. Die brandstof verbruik is effens beter en hy werk makliker. Asof die engine beter asem kan haal!!

    Especially if it is a turbo. The turbo will spin up easier and thus it is more reponsive. Will also bring down the EGT a bit.

    I put a powerflow freeflow on my 2.4 colt as the std boxes were vrot and I wanted stainless steel and have been happy with powerflow on my golf (although that I made loud). I told them to make it quiet as I did not want to be annoyed on long distance trips nor scare away animals on game drives or hunting trips on the farm.

    Its alot quieter than the one they replaced (the holes are gone), but I do not feel an increase in power and my consumption has remained the same. Perhaps it was not well designed, as Henris suggested.

    Just to give you an idea. I buy mandrel bends from TNT to use on my xhausts.

    To build an xhaust for a car normally will take us a whole day.
    Making sure that it doesn't hit the underside of the car.
    To make sure it is tucked in under the car and won't snag anywhere.
    To make sure that there are no restrictive bends.
    To make sure that there are no blobs on any of the welds, inside the pipe.
    To make sure that the xhaust is secure and won't fall off.
    To make sure that when the car is on a ramp or a lift, I am proud of the result.

    I like the pride you take in your approach.
    If ever in Moooosina, I'll visit you for a 63mm pipe on the Isuz.

    I don't build them commercially. I just do my own. But yes you are welcome to come and I will help you.

    WELL DONE Henris

    BIG problem everywhere these days is that people have no pride in their work. TOO many hit and runs and then they do not understand why they don't have repeat business. i believe that the loyal customer is the one that pays your bills. if you are lucky you also make the best margin on him because he is prepared to pay for what he gets.

    You up for a system on a Prado? or is this a sideline for your own vehicles you do.

    I will build it, but do you really want to come this far? Why not try Tom at TNT in Germiston?

    I am about to redo my LC xhaust to a 75mm pipe. This will be a nice challenging one, seeing that some of the spaces are a real tester.
