I've done this with bikes but am not sure if its a good thing to do for a car's exhaust system.

I recently bought a used fujitsubo titanium exhaust system, a tomei downpipe and a bored up extractor and am wondering if I should tape up all the holes and spray or pour in lots of degreaser/contact cleaner, seal it up and leave it overnight and rinse it with water the next day before installing them.

Whats your take on this? Is this a total waste of time(and degreaser)?

The result I get from this from my bikes exhaust when I pour the content out the next day are huge pieces of carbon and particles. Felt good when I see that.

 

should work... dont see why not do it and let us know

 

Well some people told me its a complete waste of time and I should just give the car a hard wack to clear the carbon in the exhaust. Wondering if anyone else does it.

 

Any other opinions on this?

 

Going ahead to try this, will post up pics soon

 

You can use brake dust cleaner to clean the outside and inner tip but dont waste your time trying to clean the inside of the entire exhaust pipes. There are no worth while advantages of cleaning the iside of the exhaust, just a waste of time.

 

i vote waste of time

 

go wot !
should clean up all that carbon build up ha

 

^ Exactly!

Anyways.. if ya did do it.. would like to know the results!
