I am wanting to quiet down my exhaust, the biggest 3" i could find was 24" case 30" overall oval magnaflow, it is a SI/SI muffler. I am just wondering how quiet it is.

I have the 22" 3" si/so on the stock piping with the manifolds still there. Probably as quiet as stock. No drone at all.

I had that muffler on my RCSB Hemi Ram back in the day. I had Pacesetter LT's, off road y-pipe, and dumped right before the axle. It sounded really good and had little to no drone in the cab. Although my muffler, if you looked into it, it split into dual on the inside and then back into single.

i have one on my truck it is very quiet, i am running bassani mids, stock y pipe with cats, and 3 inch back to it, with it just dumped. no drone at all 1600-2200 rpm is nice and quiet had a flowmaster before it and it is really nice to hear the radio or carry on a conversation in the cab without yelling.

i just bought a 3" C/C - 5x11 Oval 22" Body MagnaFlow Muffler SS 12579, hopefully it should quiet things down ALOT!

i think it is the biggest muffler you can get as the 24 is 5x9 and the 22 is 5x11. i think you will like it. i have it on my stock 08 chevy and it is quiet as can be. let us know how it sounds catless....good luck...rob

I would be interested in one of your old mufflers. I just put LT's with the off road pipe and my current 18' 3' Magnaflow and it is also WAY to loud.Let me know if you want to lose it I'm local.

Corey, I have that same muffler for sale (used) for $50 if you want to save yourself some money. I also have a Silverado SS tip for sale as well. Here's how it sounded on my truck with OBX headers and the 224/228 cam.
