has one with 2 1/4 pipe.....but I suspect it isn't quiet.

Newb here...please be patient if I've phrased the question incorrectly or you need more details.

Thank you in advance.

I have the 2 into 1 magnaflow muffler that I got from BC a few years ago.
Looking at its internal construction... it's actually a 1 into 2 (which is much more common) but since the design is a straight pass-through perforated internal with packing... it really doesn't matter that we're all running them backwards.

Now on the sound question? It was fairly quiet and subdued for about two months... now it's as loud as any other pass-through design muffler that's been broken in.

I've got the WH shorty headers, 2-1/2" diameter down pipes into the muffler, and a single 3" diameter pipe out the back.

Sometimes when I'm tired of the volume level screaming down the interstate, I ask myself, "how could I expect it not to be loud!".

Honestly, I do plan to swap out to a quieter muffler at some point when I'm working on exhaust stuff again.

Walker quiet flow 2 into 1.... Comes in stainless.... I think its listed as an OEM replacement for GM trucks.
I have TBP Long tubes that go straight into the Muffler and a single 2.5" behind the passenger tire with a 3" polished tip on mine... Still sounds like a V-8 but doesn't scream or cackle... Sounds pretty much like a stock truck with a little burble... Couple other guys on here suggested it when i was looking...I've been very happy with it. Its a lot longer than the Magnaflow though...

X2 on the Walker! I bought one to replace a fart-pipe on my Chebby Lowes truck when I bought it. I like a quiet sound and Walker delivered. I would say Walker is the quietest muffler you will find.

Gibson Superflow and the Flowmaster Super 50s are both Chambered mufflers that last and both can be had with the 2 into one design. They have a nice rumble with NO popping or crackling like others have.

Quieter than the Magnaflow. Even the longer one.

cant see how a flowmaster is quieter than a magnaflow

There are several different Flowmaster chamber quantity configurations that don't use packing as a sound dampener, and I THINK most of the Magnaflow mufflers use a perforated inner pass-through guide with packing that can degrade over time.

You could always do a 2-1 Y and run a single n single out muffler and have a lot more choices. Will take your Muffler shop 15 mins to built it or you can just buy one.

Correct with flowmaster. They do not use packing material as it is a chambered muffler. The packing material in a magnaflow quiets the muffler down. I haven't seen them degrade as i haven't kept a vehicle for that long of time to know.

A longer magnaflow would be quieter if there is enough room. I am thinking of going with a 2.5 dual inlet/outlet (built in x) magnaflow with side exit exhaust. In my experience, a chambered muffler (flowmaster) will always be louder than a packed muffler (magnaflow).
