Help! Getting carbon build up....

I saw a site that showed how to get the carbon build up out of the exhaust pipe but I can't remeber where. Does anyone know how to do this. My cousin and I need to know because it's all shiny on the out side and black on the inside. Please help.

stick a water hose in ur tail pipe and rinse it out:D


actually i dunno....i thought if u redline ur car it'd kinda clear up carbon build-up:confused:

I used a water hose and reg detergent. It didn't help. It is the black stuff inside your pipe. Maybe I'll post a pic of what I am talking about in a few.

is your exhaust stainless? if it is get some Mother's brand polish... its in a little red can with a white lid... slap some of that one and polish it away...

scrape it out with steel wool. Watch out it might get your hands a little dirty:D
