The exhaust on my 172 is really noisy when it is warm.
It looks like the standard system and looks in very good condition but it is so damn noisey when it is warm.
It's rather raspy and backfired the other day yet it does not appear to be leaking.
Would an emissions light come on if the cat had gone?
