This muffler has a very good sound. I am using the 2 1/2 inch tubing and duel exhaust and the mufflers sound great. They are a little loudr then the regular 40 series.

Pros: sounds great, grumbles
Cons: a little loud when picking up speed
Recommended? Yes

Comments: this muffler has a throaty sound, and makes people turn heads when your going by. it sounds great when your driving and has low resonance when at cruizing speed. the only problem i have is that i instlled a kickdown tip so it exits under the cab so it is louder.

Cons: Hard to sneak out
Recommended? Yes

Comments: I got this super 44 exhaust a little while ago and have been super happy with it ever since. It has amazing sound at start up! and the idle sound very beasty. I have a 5.2 liter v8 so i recommend it on the engine i havent heard it on a straight six or inline 4. I would definatly get one if these if you dont have one. When im at a stop light and i punch the gas you can hear my car down the street.

Price: $230.00
Pros: loud as all hell with that staple "flowmaster sound"
Cons: With a cat delete, the droning can be a little annoying on the inside, in mid-second gear, but other than that, nice and quiet.
Recommended? Yes

Comments: * PRiCE STATED WAS FOR THE TOTAL INSTALL VIA LOU'S CUSTOM EXHAUST, NORTH READING, MA* The build up was: removed collector precat (precat delete pipe) stock cat 2.50" mid pipe, flowmaster super 40, 2.50" open bent tailpipe, to a welded 4" magnaflow chrome tail truck tip.

Price: $240.00
Pros: Less airflow restriction, Louder sound (Haha),
Cons: Sometimes can be a little to loud at night....say at like 3 in the morning
Recommended? Yes

Comments: The only reason my exhaust is loud is due to that i took the cat-converter off so it goes straight from the Y-pipes to the muffler and out either side before the back tires. Overall I'm very pleased with it. I do recommend getting a K&N air filter as with any new exhaust system could screw up your gas mileage. And if you don't want it extremely loud, then keep the cat-converter (whatever brand you prefer if you don't want a stock one)

Pros: great sound, good price
Cons: none
Recommended? Yes

Comments: I got this muffler put on when i found out my stock one had a hole in it. I love the sound of the v8 with this. What i love about this muffler is that its loud outside the jeep and when accelerating, but while traveling at highway speeds and cruising, the muffler is not anymore noticeable than the stock muffler. great muffler

Pros: Looks great and sounds amazing.
Cons: None.
Recommended? Yes

Comments: I have this muffler in a 2.5 inch exhaust with headers and a high flow cat. This setup leaves for an absolutely amazing sound. At low RPM it sounds like a small V8 or diesel inline 6, and in the higher range sounds like a $200,000+ exotic such as a Maserati or Lamborghini.

Price: $210.00
Recommended? Yes

Comments: For starters if all you want is sound this is a 10. It gives the 3.8 a little growl across the rpm range. That being said performance gains were minimal so as long as you don't expect to much in that category its a good buy.

FlowMaster Super 40 series
Price: $80.00
Pros: Doubles as a skidplate. sounds great
Cons: Increased resonance inside cab, not bad at all though
Recommended? Yes

Comments: Used to run a 2.25" 40-series delta flow with no cat on my XJ. Had a very aggressive tone, but droned pretty bad in the cab.

Decided my TJ needed some sound, so I deleted the catalytic converter, and put a FM Super 40 2.25" muffler in and attatched it to the stock tailpipe.

The tone is not as aggressive, but the interior resonance is so much less than a regular 40 series.
Sounds better than any cat-back I have heard.
