Whats this on my exhaust?
Hey all,
ive just been looking at my exhaust, as the car is 7 years old now, so thought it might be starting to rust, but its not
however when looking at it i found this....
just wondering what it was, my grandad wasnt to sure and hes a mechanic, granted retired for a fair while!
the bit thats dented and is coming off to the side...

The attenuation of large-amplitude waves effected by silencers of the so-called Helmholtz-resonator type is envisaged as being due to the finite efflux of gas through the holes of the silencer with resulting partial reflection, and hence reduced transmission, of the incident wave. Quasi-steady, one-dimensional flow arguments are used to predict the attenuation, the flow conditions being assumed reversible and adiabatic, that is, isentropic. This latter assumption is avoided in an alternative method by assuming a knowledge of the relationship between pipe Mach numbers and the pressure difference in the pipe across the holes. Indicator diagrams resulting from single pulse experiments are, in general, in good agreement with those predicted.
System is stainless steel I believe so it does not rust
much.

much.the standard exhuast is stainless? awesum!
