exaust system

having smoke thinking i m gona clean whole exaust system. but dont know how to start any idea will be appreciated thanks..

What sort of smoke mate? Not a great deal you can do to clean an exhaust out other than replace it. If your getting smoke your problem will lie elsewhere.

Maybe a decent run at hwy speed might burn some soot off but as Nissannewby said problem could be elsewhere. originally I thought you were having a choof then decided the exhaust needs cleaning, hey but thats me

I remember changing an engine in a laser years ago and the old engine had left the exhaust full of oil so i took it down to the industrial area at night one lap was about 3 klm.s and i could barely see for the smoke from the previous lap
After about 5 it cleared up .

Hi thank you all yeah smoke reason not only exaust ... i gona replace my nozzle also i will do tappet adjustment ... as because i heard previously after clean exaust allsmoke vanish... so can anyone give me some idea how to clean it... after remove it should i wash it through hose water or something else ... thanks
