Flowmaster sound

[Black-Z71]

Does anyone have any experience with a Super 40 Flowmaster? I am comparing the interior sound level of a 50 Series, and a Super 40 Series. I like it loud on the outside, but not on the inside. I have a 50 Series catback now, and I'm thinking about changing to the new Muscle Truck Exhaust System.

 

...and yes I've seen the posts that say Flowmaster sucks...

If the tips are coming straight out the back and not diagonal the interior noise isn't that bad. I keep my radio on so I barely notice it.

I've got the Series 40 muffler on my '66 Mustang Fastback. It sounds AWESOME on it but it would be a little louder than I would prefer on my '05 Crew Cab. That said, if you like the Series 50 but it just isn't quite loud enough, then the Series 50 should be just the ticket.
