    Hi Guys I am looking to get a remap, LSD fitted and a secondary cat or resonator removal.

    Whats the noise diference between just a resonator removal and the secondary cats and resonator removal if any?

    What seems to be the favoured method with the guys on the forum? Apologies if this has been covered loads before.
    Thanks

    There's quite a lot of videos on YouTube for you to look at mate; albeit it's not always an accurate representation of how an exhaust sounds.

    Just had my secondary cats removed and replaced with Milltek pipes.

    IMHO it brings the noise out nicely without being OTT. On cold start its reasonably loud but then it settles and sounds how it should have done. The standard car was too muted (albeit that was probably a plus point to some) when cruising, but now the growl is out and when you give it some revs it barks loudly. When on open throttle it sounds really shouty :D The pops and cracks on the overrun really come to life as do the cracks on high rev gear changes.

    I'm over the moon with it!

    I'd imagine just a resonator removal would give similar results and removing both would be a bit much for my liking but sure others have done it and like it!

    I believe a remap will make the car a tad louder - but others can confirm that.

    I can confirm, the remap does make the car a little louder - more of an induction roar than from the exhaust, on account of the intake flaps being allowed to open fully.

    Secondary cats sorted, for me at least, is a must in the w204 c63. Sounds fantastic and I especially know as I had mine put back to standard and it's sorta dissapointing now after being so used to the previous sound.

    I would say it still retains OEM sound quality and doesn't sound too aftermarket.

    PS - I wouldn't do both resonator and cats together. I would go with the cats approach but understand the potential mot implications of removing cats from cars.

    DuncS3 why would you not do the resonantor and secondary cats together? I dont need to worry about the MOT as I have a friend who would sort this. But also dont want the car to sound ridiculously noisey.

    Only because I haven't heard both together and as said earlier by Mole, it might be too much. Maybe try it in stages. Otherwise, depends how loud you want it.
