I had a 2.5" FlowMaster 40 series si/so made into a 2.5" di/3" do. Talk about loud, it was obnoxiously loud. Driving in the city, I would set off car alarms 2 blocks before I reached them. It was too loud, the drone drove me bananas.

flowmaster single chamber, i had mine on stock manifolds and it was way loud sounded tough like a muscle car. I actually would be willing to get rid of it pm me if interested.

Flowmaster doesn't make a single-in dual-out single chamber.

Ferocity02 you got the wrong flowmaster I had a single in dual out 2 chamber 40 series it was pretty loud. After I got my headers it got to droney so I ditched it for a magnaflow and now I'm too quiet

Yeah, after wading through sound clips I think my muffler is an American Thunder series. It's pretty quiet, it sounds almost like stock at idle, and drones like hell at 1900-2200rpm. I might go with a Flowmaster Super44. I agree the Magnaflow is too quiet, especially on a stock header/cats truck, but they do sound nice and refined. I am still contemplating just welding in a bullet and and splitting the pipe so I can run two 4" tips out the side.

So your truck has dual cats two into the muffler one out stock right? So why not run true duals with Xpipe and some bullets or if thats not loud enough an Hpipe instead(much louder than Xpipe)??

for one all these trucks run dual cats into a single muffler. unless you make mucho HP you will lose power with true duals and the x-pipe usually quietens up the exhaust. I had a crew cab with LT's stock cats, true duals with an x-pipe and dual bullets, and it was very very quiet.

No, the setup right now is stock manifolds into the stock y-pipe with stock cats, merged into a single 3" intermediate pipe into the single-in single-out Flowmaster muffler, then over the axle and out behind the rear tire. This exhaust is basically exactly stock, except with a Flowmaster muffler in place of the stock one.

I was considering cutting the merge section off the y-pipe and welding in an x-pipe, then dual 2.5" with bullets out the side, but on a stock truck that's pretty much a waste of money. It would certainly cost more than just buying a single-in dual-out muffler. Right now I'm leaning towards the Flowmaster, even though my truck will sound like every other one out there.

Anyone have a Gibson muffler? How loud are they? Sound clips?

Ok, I just got of the muffler so I'm just running an open I-pipe. It is the same loudness I am looking for. But it kind of sounds like a boat. I think a bullet will help that a little bit.

you have a sound clip??
kinda wondering what that sounds like
