Cleaning Exhaust

[nuffsaid]

Hi all

I have a used cat back system for which I would like to clean the inside.

There is alot of black soot and crap in the pips and muffler.

Whats the best way to clean it out?

Note: I dont want the insides rusting on me! so maybe water or something isnt good?

Thanks

can of degreaser + water

when you start the car in the morning, condenation builds up anyway.. so water isn't going to be too big of an issue

just make sure it dries fully (ie place n the sun to dry)

Petrol?

I know what you mean.. Can get a pretty solid build up, like can minamize diamiter a bit when its bad

Yeah wonder if its worth it at all.

Might end up clogging it with black soot seeing as its pretty hard to get degreser into the middle of the pipe etc.

I can totally understand why you want to do it you pedantic bugger but it would be a tatal waste of time because as said within 2 weeks or less it will be lined with carbon again anyways. Also washing it out is a big no no because no matter what you do you will not get it out of your resonator or muffler. Condensation is nulafied because it is in extremely small quantities and Hot exhaust/exhaust gas makes quick work of that.

But if you wash it out the pooled water you couldn't get out will sit for ages and your exhaust will die of internal cancer

Unless it is blocked, don't bother as it will have no effect on note or performance

Settled then, that was easy.
