Anyone on here looking at what mufflers to get can add these to their list. I've been running a pair of flowmaster super 10s on my exhaust, and flowmasters in general for a few years now on my F100 with a stock 390 (intake, carb, headers). I liked the super 10s but wanted to try something "new", and bought a pair of dynomax bullets. Needless to say the sound was impressive and I'm going to keep them on there.

Here's a vid although the GoPros sound quality isn't all that great:

 

Col beans! Hows it sound on the highway?

And true duals or x-piped?

 

now i wish i had got those back in 2008 when i didnt!

 

Sounds Great. I just put some Magna Flows and pipes out the back on mine and you cant hardly hear the truck. Now it had two completely blown out mufflers (The entire bottom of both Mufflers were blown open) and pipes strait off the Manifolds so anything next to that would sound extremely quiet. After standing behind it and listening to it, it sounds pretty good. Kind of a low throaty sound and barks when you put the pedal to it.

While bullets do sound great, they are simply overpriced glasspacks. I believe there are a couple companies out there that still produce perforated core glasspacks for a reasonable price.

Thanks! I've only been able to rev it a little because it doesn't have insurance right now. And it's only true duals although I plan to have new mandrel bent pipes installed next year with a possible crossover depending on how and where I want the pipes ran.

 

Thanks to everyone else. And I've literally said the same thing on the F150online website "overpriced glasspack". I just wanted to give them a try because they all made it sound amazing, which for the first time ever they were right.

 

BTW I took it out for a spin around my neighborhood area and got the engine to operating temp and opened it up...Boy does it sing! Sounds real healthy and deep once it's warm and I can crack the throttle.
