Louder exhaust note after timing belt change

[LTC GX470]

I recently changed my timing belt in my GX 470. The exhaust note changed to a more throaty tone. Is this normal? If not, how can I get the more quieter GX back. Thanks, LTC GX

Others experienced a ticking noise. If this is the case, try removing the serpentine drive belt and inspect if the sound is still there.
