Hi M.Scotty
I did asked you this on your live youtube couple days ago and u answer but i realize that my car is using a Racing Headers 4-2-1 formart that removes the catalyc Converter so im afraid the noise is not from a broken parts inside of it as i explain before the rathling only happen after a cold start now i notice if i just leave the car off for a bit lets said 1 hours and when i rev the car the noise comes back but only while i pressing the gas as soon as i lift the gas even if the engine is stills let said over 3000 rpms the noise stops right away
Well, I could easily be a worn timing chain. They will do exactly that. You want to pray that it's not a problem in the cam system because when they rattle cost a fortune to replace the cams and the bearings and any variable valve systems parts
