    TD5 Exhaust Modification

    Hi All,
    there has been talk of it but the nuts and bolts is what I wish to know,
    Apart from the increase in noise; is removing the centre muffler and replacing with a straight through piece on a TD5 beneficial???????? as far as power increase goes or responciveness of throttle (less Turbo Lag)????

    I dont really want more noise but if there is a power gain I will do it.

    Particually with an ECU and intercooler upgrade ??????

    Thanks
    Piddler

    The couple of people out here in Dubai who have replaced the centre section with a straight thru peice say they hav`nt noticed any real difference in performance, just noise, the seem to like the noise and are happy with the mod.

    I have a manual TD5 D2 which has a BD remapped ECU and I removed the muffler and resonator.......much more noise (too much noise IMO) but yes it has improved the turbo spool up slightly. It is very slightly though but I do notice it and this is enough for me to put up with the noise. Perhaps next year, I will look at re-doing the exhaust and trying to quieten it down at the same time.

    Cheap way to improve the spool up though, cost me $50 for an exhaust shop to chop out the muffler and weld in a pipe.
    '99 Manual TD5 D2.......heap of money spent on it and it has ended

    I've done it. If you look for it, the turbo spools up very marginally quicker, but its just noiser really and not really a power gain. Sounds cool, and I've had the odd comment from others.

    This all said, I am considering refitting another muffler back in.
    Cheers

    That surprises me considering the shape and sheer size of the thing you'd think it would be a tad restrictive
