    OMG,
    I have spent a while reading lots of different posts and have just managed to confuse myself.
    At the moment, the only mod. i have done tuning wise to my 325 is a free flow air filter. I would like to tune for more power but don't know which way to turn 1st. Exhaust & re-map seem logical but there is lots of ideas out there like an M3 exhaust, 330i inlet manifold.
    Can someone give me some relevent advise please.

    Thanks

    I don't think you'll gain much from a 330i intake, as your 325 is already one of the full fat unrestricted engines. There might be a couple of BHP at high revs in it, but only if the inlet ports are the right size to match the 330 manifold.

    The e46 M3 exhaust is a complex bit of kit, not just a simple swap-

    exhaust not even really required either.
    just try the remap and see how that feels
    what i've felt,what i've known
    never shined through in what i've shown.

    Just had a remap last Sunday and the car is much quicker off the mark now and much more responsive.

    you beat me to it!, bmw exhausts are nearly the best you can get anyway!, not really any gains to be had from an aftermarket exhaust!

    He came to me and was on he's way to a course for a while. Cost wise was £200 as per my April's latest offer in my forum section. Opted for MAX performance on it and it seemed to be going very well indeed

    I remapped my brother's e39 (525d) last week and it absolutely flew. I agree with everyone else about the exhaust. You may get a partial cosmetic upgrade but not the performance. The remap will give power, performance and improved fuel economy. There are not many mods that can combine all three of those factors.
