    Default 360 white powder coming from silencer

    I've just picked up a used stock muffler to replace my anti-socially loud one I have on the car (it came with it - not sure of the make).

    Anyway, the stock tips I have seem fine and the valves appear functional, but there's white powder coming out of the outer stainless steel wrap on the muffler box. What's inside a stock exhaust ? I presume a simple box which is then wrapped in some kind of heat material then the whole lot has the outer stainless wrapper with the "no touch" hand stamped in it.

    I guess the heat layer is disintegrating so is this a big deal and is it common ? What are the implications if I fit this silencer as I really want a stock sound - I have my reasons.

    thanks

    This feels like the sort of question that may have been asked before

    Did you not find any other threads ?

    Hi Lee, it is the insulting material escaping from the exhaust, I've seen lots of them with signs of residue, not sure how serious and issue it is other than coating your inner panels and engine in White dust.

    Exactly how anti social is the exhaust that's fitted? Is it louder than Rich's spider?

    I see some post but not lots. It appears to me more of a cosmetic annoyance on the 360 then anything.

    Anyone opened up the outer wrapped and removed the remains coating ?

    Neil,

    I reckon it's the same as his spider. I need a stock sound as the car is stored at my in-laws so there's an extra level of courtesy required. If I can't store it there, I can't have the car.

    The exhaust is on it's way out - the white dust is the packing leaking from the centre seam. It will only get worse.

    You mean the inner box is probably leaking ? isn't it stainless steel too ?

    So then has anyone got a factory stock silencer for sale which isn't dropping white powder ?

    thanks

    TBH I think they all do it, design fault. So you could in theory but a new one from Ferrari and in x months time have the same issue. Is there no way to repair these? My exhaust also puffs white powder.
