    Of course now it is in, it has made extra power and flattered off the power curves very nicely.

    I haven't fitted an EGT gage yet and removing the cat was the best advice I could get on how to lower those temps.

    Pete Bell has assure me that there is no issue with EGT’s in his testing but as I tow a van from time to time, I find that I am using large throttle openings for up hills and just want to be safe as possible.

    Cheers
    Alive tuning sell a mid pipe replacement for defenders with a straight through reso in place of the muffler to improve flow and keep the noise down.

    Hey Drover,

    Just wanted to ask, does the old pipe have studs at the turbo end?

    I have my pipe delivered from alive and got all excited, removed the heat shield and stopped, I have M8 nuts and bolts for it that I bought, but was just curious what was on it, it looks like it could be difficult to get a spanner underneath to tighten them up, but was hoping once the cat is removed then there would be enough space and visibility yo get to it from underneath.

    So how did you fix yours on?

    cheers
    Pat

    Hi Pat,

    Once the cat is removed there is a enough room for a socket on an extension to reach the under side of the turbo.

    I had the missus hold a spanner on the bolts from the top.

    Made up some basic brackets out of aluminium to attach the factory heat shields.

    All good.

    Cheers

    I just used some 2mm plate. Easy to bend and cut, you got to love working aluminium.

    One piece bent around the cat to form the right shape to go around the bottom of the heat shield and then extending down to one of the spare bolt holes on the engine block. (looked a bit like a boomerang before you put the bend on one of the arms)

    A second piece bent to clamp around the pipe and then leading to the other end of the “boomerang” around the heat shield (this was just a straight strip)

    Good luck

    I have done a few things over the last couple of years that could potentially negate warranty claims, but the Stealer hasn’t mentioned them and my warranty repairs continue.

    Cheers

    Crikey mate,
    what warranty issues have you had and needed to repair.

    Cheers.

    Robert.

    Not much really,
    Broken rear seat clip
    Broken sun roof latch
    Rear diff pinion seal, just once
    Had stealers chase a vibration but that was caused by the 2" lift
    Water egress issues

    I think that is very good run over 3 years
