Flowmaster Muffler Series Question!?
 
So I plan on buying a Flowmaster Muffler, but I can't figure out what the Series numbers mean. Theres Super 40, 50, 60 and such.

The lower the number, the LOUDER?
I want a beastly sound, but not abnoxious sounding.
In between quiet, and loud.

I have a 1999 Grand Cherokee Laredo. Inline 6, 4.0 L.
The outlet needs to be 2.25 I believe.

Not sure which I want or what are the differences.
Super 40 Series 2.25" C/O
40 Series Delta Flow 2.25" C/O

50 Series Delta Flow 2.25" C/O
50 Series SUV / Perf. 2.25" C/O

Help please? :)

I believe the lower the number, the smaller and louder it is going to be. I would throw on a 50 series if I were you. Be aware that Flowmasters are notorious for drone. If drone is not for you, then do not get it.

So If I got a 50 series, it sound like this.

Dont do a flowmaster, Get a magnaflow or borla. The drone will give you a headache. Especially on the highway.

I had a 50 series on my '93 ZJ with the 4.0. No drone at all and it made it sound really good.

If you love drone and loudness like I do, install what I installed. A Dynomax Bullet Series muffler and have the reso chopped off. :D

I have a dynomax on mine and it give a great low tone and acceleration note. Although i do get a drone at highway speeds, 55-60mph, that i wish wasn't there. I got used to it.

I have a Super 40 on my H.O WJ's V8...I love it..but it is loud....

I'd say go for a 50 SUV or Delta Flow since you want in between Andy...

compare the interior and the exterior sounds they make. It would also be helpful if you can hear the actual sound. But they have sound clips installed on 8 cyclinders, so that too would sound different from our 4.0

hope that helps!
