Anyone have experience with both? Tough shopping for mufflers when you really don't know what you're getting till it's installed. I've heard loud chambered, quiet straight-through, and vice versa... so I really don't know what to expect when it comes to these specific models.

Like the rest of the world, I'm simply looking for a little idle burble, WOT throat, and highway silence. Minute, insignificant performance changes are not a concern - only looking for sound.

Considering 4"x9"x18" in either configuration. To avoid any unnecessary discussion (other brands, other sizes), only one of these two I've linked are in the running:

Chambered
Straight-through

They both have unique sounds that only you can decide which u like better as its all preference. I prefer the straight thru sound Vs chambered. The hardest part is getting "highway silence". In my experience, magnaflow and most aftermarket performance mufflers drone. But it will depend on your vehicle. Good luck.

Chambered mufflers are louder than the straight through, but a different kind of loud. I would describe the chambered as throaty/raspy while the straight through has a deep powerful sound. I've heard both on a crown vic. My personal preference is the straight through. Youtube clips (with headphones to help with the bass) can be helpful.

If you have a shop in mind to do the sale and install, ask if they will hang each on (not welded) and let you listen on the rack. I"ve done it before, usually not a problem.

I have the "wide body" HUMONGOUS Magnaflows in full duals and Hooker headers (5" by 11" by 22" body) on my 406 SBC truck. Very nice sound. Smooth but like others say, they do drone at cruise some but I don't mind a little. Every engine and every bend and every muffler sounds a little different. A tough call from a computer.

I recently saw a video comparing the 2 and the straight through made more power but was louder. Even when down sizing the pipe. So loud and more power or quiet and less power?

In high school I loved loud exhaust. Now stealth is the name of the game. Loud exhaust seems to only attract attention from cops.

I'd go with the chambered muffler because there's a chance the chambers will reduce drone causing resonance and there's no packing to degrade.

Straight through like a Borla sound the best on a mod motor IMHO.

Borla or Magnaflow. Anything chambered like the Dronemaster sounds awful IMHO.

I don't know if Magnaflow has changed their design on their straight-through mufflers recently or not. The last time I checked, (about 3 years ago) their straight-through mufflers with case lengths over 18", they used a two-piece tube poorly welded together in the middle of the muffler. It was a design that is almost guaranteed to fail, and they often did/do.

So if you choose one of their straight-through designs with a case length over 18", inspect it closely to see if they are still using a two-piece tube design, before installing.

Chambered has no place on a classy Crown Vic imho. Leave those gutted tin can chambered dronesters for the Mustang brothers.

Borla makes some nice and durable hardware if you can swing it.

I'd suggest glasspacks, long glass packs. Won't be popular on bitog. With the factory cats, its not that loud.

I have them on the olds, and the avalanche.
