Just curious about other trucks with the 300 six. My truck seems to be really loud from the engine. Even though i have a cherry bomb on my truck it seems louder up towards the engine. Are these engines known for Exhaust manifold leaks it's most likely the stock gasket so it could be time to replace it. Is it a pain in the butt?

 

Not as bad as trying to do a set of V8 exhausts while still in the vehicle, so, relatively speaking,
no.

 

Exhaust manifolds do crack sometimes and if your truck is pre-EFI there is a 'donut' gasket between the manifold and exhaust pipe that can burn/blow out.

 

I have EFi i'm just curious because it sounds a lot louder from the motor instead of my exhaust which lets out right after the cab
