Today I installed a flowmaster super 44 and dumped it rite off the end of the muffler. I just cut off the stock muffler and put the flowmaster in its place. The problem is it's almost as quiet as the stock exhaust at idle it starts and has a nice rumble but when driving I can barely hear it all, all I can hear is a wooshing noise thats kinda annoying. My friend has a 2002 chevy 5.3 that does the same thing and is just as quiet

I`ve never heard anyone say a super 44 was quiet. It`s always the opposite, too loud with way too much drone.

I have a 50 series with 2-1/2 inch dual tailpipes with 4 inch tips and it`s pretty damn loud.

Yea me either, that's why I can't figure out why I'm the world it's so quiet. The only guess I have is its something to do with the cats

I agree on getting the Super 10 instead or just cut pipes if loud is all you're looking for.

Every once in a while I hear someone complain the 44 or 40 is to quiet. Typically, the muffler is either installed backwards or the converters are clogging / clogged.

I believe the the cats are starting to clog because the muffler is installed right its not backwards. I'm not looking for something crazy loud I wanted something in the middle between stock exhaust and straights so I opted for the flowmaster, it sounds like it hasn't hardly gotten any louder except at idle. How can I tell if the cats are clogged?

I just cut mine off, I had a 50-series and it was pretty loud, and droned a lot. I replaced it with a Bigger Magnaflow and it quietened down to a low rumble, and the drone almost completely.

That is strange, because I have never had a Flowmaster on any of my trucks be anything but LOUD.

As far a clogged cats, your truck would be acting up slighty or majorly depending on how bad they are clogged....you would know it, or in my case just last week, completely clogged left cat & made the left cylinders mis-fire, my Yukon wouldnt go over 40-50 mph the final morning on the way to the muffler shop, and the loud tapping noise (the cats). (The quiet ticking started weeks ago and then by last week, sounded like a tractor idling. Definitely a gradual process.)

But I will say that after I put the new cats on, now the "quiet" magnaflow is a lot louder and the drone is back lol, oh well, still isnt as bad as the Flowmaster previously...

just a heads up flowmaster i never use anymore due to chambered design and id look at magnaflow. Straight thru and ive heard this whoosing noise before on the 5.3s tahoes and trucks from flowmaster.

PM me if you decide to change it out because you will be happy with a magnaflow muffler

I'll proably end up looking into magnaflow once this flowmaster gets on my nerves enough. I have the whoosing noise to from the flowmaster once I really get into it is very anoying, but I really love the roar you get with them when just cruiseing but hate the sound once I give it some gas. I love the way magnaflow sounds on other vehicles but it seems on 5.3s they sound like a old set of glasspacks. If I can find a straight-through magnaflow that gives me a roar that doesn't pop like straights I will get one. I'm not concerned if it's too loud I just don't want it to sound like I have straights

In my opinion the Magnaflow's are awesome. I had a smaller 14" magnaflow on my TBSS and it didn't sound like old glasspacks, it was raspy and roared, and sounded better than my Flowmaster, it had some popping, but didn't crackle like a G-P. I stepped up to the bigger sized Magnaflow and that decreased the sound characteristics as far as popping/crackle but still sounded good when getting on the throttle.
I'll try to get you a video clip up later of my Yukon with the 18" Magnaflow I have on there, you would probably dig it on your truck, and if your cats are clogged you could have all of it done at once at the exhaust shop..

I know this is the Tahoe/Yukon forum, not the tBSS Forum, but it had the 6.0, my Denali has a 6.0, and they sounded very identical... This sounds better than a GP to me:

Flowmaster with healthy cats as you can see, definitely not quiet: (and it was this loud on the Yukon recently before I replaced with Magnaflow)

Hopes this helps... and trust me, you wont be disappointed with a Magna...

It want let me see the videos? Was the 14" magnaflow about as loud as a flowmaster 40 is? I like how loud flowmaster 40's are, my buddy has one on his Truck with tailpipes and mines dumped but his is so much louder than mine. To me flowmasters are a good median between stock and straights, as far as loudness

The 14" 4x9 MagnaFlow will be a little quieter than the Flowmaster 40. The 14" 5x8 will be quieter than the 4x9 version.

For a straight through (free flow) muffler the Magnaflow series is pretty quiet. I love the performance factor without the drone as a chambered muffler would give (flowmaster ect) . As an exhaust shop manager i Constantly switch lol
