Need sound clip for 1966 289 using Waldron single exhause with resonator

We have owned our 66 since new, There are sound clips for various exhaust sounds but all seem to be dual exhaust.
Our car was single exhaust and I am consudering the Waldron system mentioned in title. I am considering the mild imposter sysetm.

Does anyone have this installed on a 66 and if so coud you get a recording of the sound please? I would like to order ASAP but want to insure the sound is not too far off. Justthinking for a slighgt beefer sound.

Thanks!
