Price: $95.00
Pros: Nice deep sound
Cons: None
Recommended? Yes

Comments: I purchased the super 44 series muffler at advance auto parts. It was roughly around $90 dollars. I didn't worry about what inlet/outlet position to get because the muffler shop will put in pipes to make it work. I made sure it was 2.5" on both ends because that is what was recommended on this forum. The shop charged me about $50 dollars to put it on which includes the piping they had to use. Overall the total cost was around $140. At first when I started her up she didn't sound that much louder/deeper (I guess I had very high expectations). However when I drove her down the road it definitely had a nice deep sound, no drone and under normal driving it is not annoying at all. Over time the muffler actually got much louder/deeper sounding which happens to all mufflers after they are broken in. I love the sound as it is very nice and deep and not annoying. I highly recommend the super 44!

Comments: Custom 3" single cat back w resonator removed and this muffler. I have gotten compliments from lots of people about how my truck looks and sounds. Of course it was close to 500$ cuz the cat back was custom and I hate exhaust leaks.

Pros: Great throaty sound that isnt ear splitting.
Cons: none so far
Recommended? Yes

Comments: I replaced the factory muffler with this and left everything else stock. It has a nice rumble to it, almost no drone which I really like. I've also noticed a slight extra umph when I hit the gas. If you want a nice growl and low drone, get it.

Pros: Pro's? Just about everything.
Cons: None
Recommended? Yes

Comments: I had a magnaflow exhaust for awhile but it just wasn't cutting it. I've made friends with the owner at MACH 1 Muffler so I got a steal of a deal with this muffler I think. Shortly after I installed a cutcut(Y pipe) right after the cat for just that little bit extra meaty sound.

Pros: deep signature flowmaster sound in a decently small package.
Cons: none i i can think of at this moment.
Recommended? Yes

Comments: went from a dual long tube setup on my yj to a self fabbed y-pipe and exhaust. i tossed this super 44 under there and to my surprise i maintained about the same throttle response and power as i had with the dual setup. the exhaust is much quieter and a lot more manageable under the jeep over the old dual setup.

Pros: Sounds grreat! Throaty, but not obnoxious.
Cons: Zero
Recommended? Yes

Comments: This muffler sounds incredible! Not sure how to link the video, but you can take my word for it. It has a really throaty beefy sound through all rpm ranges, but is never obnoxious. Sounds unique on the linear 6, in a good way.

Pros: Great Sound , Easy install!
Cons: Non
Recommended? Yes

Comments: This was a very easy install. Factory pipe on the 4.7L HO 04 jeep grand cherokee is 2.5" All you need is a 18" extension pipe 2.5" and 3 2.5" clamps. When you make the cut toward the back of the jeep make sure you cut it before the pipe swells to connect to the factory muffler and everything will fit together great!

Pros: Great sound, very raw and mean.
Cons: It's pretty loud in the cabin and you won't be able to do any discreet or illegal off-roading very easily.
Recommended? Yes

Comments: It's very loud and has great raw, mean sound, but it is hard to off-road illegally or discreetly. I've tried. Can't tell you how tired I am of getting yelled at by fat, old people. And not the cool fat, old people, the ones who regret their lives and seek out to destroy others' lives.

Price: $92.58
Pros: DEEP and LOUD. It has the deepest tone of any Flowmaster muffler I've ever heard. I get compliments on it all the time.
Cons: Sets off car Alarms every time I start up the Jeep. Wakes the neighbors if I ever have to go somewhere at night.
Recommended? Yes

Comments: I have a Super 44 Flowmaster Muffler with side exit exhaust in front of each of the rear wheels with 3" slash cut tips.
I would say that there is nothing out there that sounds better than this setup on the WJ.

Price: $64.00
Pros: Love the sound of this thing. Roars when it needs to but is actually pretty quiet as well. Much better than the 40 series I had. Also came powder coated so I don't have to worry to much about rust. It pretty throaty too and makes an I6 sound pretty beastly.
Cons: Can't think of any.
Recommended? Yes

Comments: Purchased this muffler after my exhaust from the down pipe back literally fell off. Rusted out in 2 places and came off the Jeep. So once I purchased this I went and had it installed with all new pipe and welded up (I don't so much like the bolt together thing) and I could not be more pleased. The Jeep runs better and sounds better. I liked the previous Flowmaster 40 I had on there but the super 44 sounds better and actually the car sounds quieter at a stop.

Pros: Sounds awesome, deep tone, raspy bite.
Cons: None!
Recommended? Yes


I would highly recommend this exhaust to anyone...it sounds PERFECT on the 4.0 It has a super low rumble when started up and at idle with a low, deep tone to it. When you are just cruising it has a low growl throughout the RPM's that sounds great. It is not super loud but loud enough to be heard if you want to be and has a nice bite to it. I am not a big believer in exhaust adding super horsepower, but I definitely feel a little improvement in throttle response across the RPM range with this exhaust which was a pleasant surprise.

Pros: Amazing sound. Deep, throaty, and rich engine nice. I feel a better throttle response, less restriction so I'm running much better through the RPM's and I'm getting great attention from everyone around.
Cons: Interior resonance is a little loud, but I love it.
Recommended? Yes

Comments: Great product. ALL JEEPS SHOULD SOUND LIKE THIS WHEN YOU GET IT PUT ON!!!! Deep and throaty tone, sexy idling tone, and amazing sound on the take off. I love it and I'd highly recommend it to ANYONE with the 4.7L or the 5.7L
