Anyone have any experience with Magnaflow #12772 or 14772. Looking for a quiet muffler.

i don't know anything about magnaflow part numbers, but the magnaflow muffler in my exhaust is very quiet.

Ditto!! It's a very quiet muffler.. The only thing I didn't like about it is now I can't hear much of my turbo whistle.. But hey, as long as I have the extra exhaust flow, I'm happy!

We've sold a bunch of those to guys wanting to quiet their exhaust systems down...with very good responses!

I have the 14772 and love it, you can usually get a used one on ebay or cragislist. I wanted a valid warranty so I got it here. Magnaflow 14772. Also some of the forum sponsors selling magnaflow*usually have a sale going on. Either way its a great cat, sounds great, and very easy to install.

I have a magnaflow turbo back system on my truck and one thing that does bother me is that there seems to be a drone now when driving at hwy speed. It is constant and I have had it back to try and see if they can get rid of it but it seems to be a permanent thing with the 4 inch exhaust. The exhaust note is quiet though just have this drone inside when driving.

You might look into putting a resonator before the muffler. From what I have read suppose to get rid of the drone sound.
