Typewriter sound?

When I’m accelerating, say next to a median, I can here a noise that sounds like a typewriter. I think its probably an exhaust leak coming from the header. What else could it be? TIA

Adjust your valves??

if you car sounds like a big old V8 american car, yes, you probably have an exhaust leak near the engine… probably between the 2 parts of the header… mine was doing the same thing… the gasket was in 2 parts…

the valves really aren’t that loud, but I’ll take a look. Answer I think your right about the gasket. Thanks,

Jeff
