I had Flowmaster 40 series on my 9:1 BB, with a 2.5" dual with H, dumping downward at the bumper. It just wasn't impressive enough sound level (loudness), I actually put washers under my triangle caps to let a little sound out there.

I switched to Pypes Violators based on their web hype. They sound cool at idle and are loud enough in general, but at more open throttle, I think they sound raspy or ratty. It's a high frequency popping, not like a big block rumble at all.

I am not concerned about ultimate horsepower, I just want something loud and deep sounding without the pop. What about the FM Super 44s? Are they significantly louder than 40's? Any other ideas?

I've never heard any muffler that was louder than a 40 series...you sure they're really not 50s?

Didnt hear the sound clip but most V8's that sound that way have an X pipe.

Yup, they were 40's. I had 50's on first, in fact. They were way too quiet!

And yup, it's kind of a ricey, crackly exhaust note. Dang it, now I am going to think of that every time.

The Violator muffs for my application are offset in, middle out. I could see right through them, there was just a perforated angled tube inside.

Dynomax has a safe and sound guarantee if you don't like the sound

Loud and deep? Then I suggest Spintech Pro Streets (small case) dumped at the axle. They should be just what you want.

A friend runs them on his 10.3:1 406 SBC dumped at the axle and they sound absolutely NASTY. Way too loud for my tastes but perfect for him-- case in point, he bought a cam 2 sizes bigger than Mike Lewis and I both recommended just for a nastier idle pulling into car shows...

Also, if you want deeper tone then ditch the crossover. An X pipe (and an H to a lesser extent) both smooth and quiet the exhaust note.

I used to run the 14" Dynomax Ultraflos that some of the other guys are recommending and they are nowhere near as loud or nasty as the small cased Spintechs. Flowmaster 1-chambers are also really loud.
