TFBlackout05 I have a 05 tj 4.0l i bought an exspensive flowmaster and it just wasnt throaty enough! So i cut it off right behind the flange and cat. i just welded a down pipe on that flange! I am impressed with how it sounds! Just try running around with it disconnected from the cat take it around the block real quick and romp on it a few times! see what you think!

Wallygator I used a Dynomax super turbo on mine and it sounded nice. And they make it in a direct bolt on replacement so no shop needed. Gave it a nice rumble without being to noisy on the highway.

jeepjones Magnaflow, Banks Headers and a 4" high flow racing cat. Thats what I've got and it sounds gnarly. Nothing on the road that sounds the same around here.

i drove mine 30 miles on the highway yesterday open header, and im using the stock intake setup and it ran just fine (except i didnt have any O2 sensors lol)
So you just cut the stock, put this in: Gale Banks Engineering 51314 - Banks Monster® Exhaust for 04-06 Jeep® Wrangler TJ with 4.0L I-6 Gasoline Engine - Quadratec
And that's it?

Cons_Table I have the banks monster cat back and love the sound as well. Not bad at highway speeds, but when you put your foot in it, it opens up with a nice tone.

Cherry bombs sound ok, but I find them kind droning at times (my buddy has one in his cherokee). I have also heard that eventually the fiberglass will burn out of the cherry bomb, leaving you with a not as pleasing sound.

I really like the idea of having that deep throaty sound on my TJ.

TORO My Jeep has a cherry bomb on it. PO had it installed. It sounds pretty good. Definitely not ricey. Plenty deep but almost sounds like a school bus to me sometimes. Not too loud with the soft top on but for some reason when I have it off it is pretty loud. Idle is the worst. Idle is super loud and when the earth is closer to the bottom (on trails) it is even louder almost ridiculously loud. I don't have a catalytic converter and the exhaust dumps out directly under the front passenger's seat. I'm going to extend the pipe out the back and see if that cuts down on some of the idle's drone. If that doesn't help I'll be looking for other mufflers. Not crazy about super loud.

vballspen are the cherry bombs super loud? what can I expect to pay to get a muffler welded on?

rockhard98 Flowmasters are a great high quality muffler and like many I love the sound. Got a set on my Ford with a built 429, can hear it coming from a mile away. Would love to put one on my jeep, especially sents I got a chunk of cat that broke loose and bounces around in My muffler.

I'm gonna end up running a rod threw my cat to brake up all the crap inside so it will flow like it ain't there, but still "look" like its in good working order. No emissions testing here so no worrys. Never ran a "high flow design" I hear they work pretty good, but then anything is better then stock.

The xtra flow will add a little more sound to your exhaust due to less restriction. Should add some power as well,can also improve your gas mileage. I beleave setting up your rig to breath should always be one of the first things ya should do.

I am slacking on that part myself lol, but its deffently on the list.

jp2611 have the flowmaster and get lots of compliments. I do have "high flow" cat though-not sure it makes that big of a difference-cat went bad (plugged) and changed muffler at same time. So perceptions all off as for improved performance- anything would be better than not being able to "breathe."

rockhard98 Your 40series flowmaster will sound better the the 44. If your not running a header plus leaving the cat, the 40 series will have a pretty mellow sound, but you will be able to tell its there when your on the peddle.

Black98 I Love my banks monster system, great sound for idle and around town, not intrusive at highway speeds (soft top, idk about it being audible for hardtop), and a nice roar when you finally get a chance to pass the idiot on the cellphone.
