If you want it to be loud just wait until the muffler falls off

I have a Thrush Welded, Performance curve cat, 2 1/2 from header back and the thrush welded drones at around 1400-1900 rpms horribly. I have my ac compressor out so I have to have the windows open and normal cruising speed 25-45 I can not hear my radio. I will be removing it next week and put a Dynomax Turbo on in its place. Acceleration and highway cruising it sounds great but I spend most of my driving on residential streets so it does not work for me.

the forum has a search function that would be greatly helpful in your quest for answers.

also, youtube had approx 1 trillion videos of peoples xj exhaust setups.

Yep. I have a 94 XJ and a 99 WJ, both with a 4.0. The XJ has no cat and a dynomax super turbo muffler and tailpipe. It has a nice rumbley idle and a nice loud performance sound. The WJ still has the stock cat and the exact same dynomax super turbo. Its almost stock quiet. Unless you hear it next to another WJ with the stock muffler, you probably wouldn't even know its not stock.

'93 YJ 4.6L stroker, AX-15, NP-231HD/SYE, 8.8in rear, OME 2.5 lift, home made front hub conversion, hydroboost. Warn M10000 winch.

'79 Cherokee Chief, 401 MPFI fuel injection, T-18/D-20 and hydroboost. Otherwise stock.

That is incorrect.

There may be other good options. I'll tell about the ones I'm aware of.

A Magnaflow stock replacement cat will allow it to breath a little better and make a little more noise.

After that I suggest a Magnaflow cat back (muffler and exhaust pipe).

It'll sound slightly mean at take off or high throttle. The rest of the time it'll be quiet (which you'd want to avoid a headache).

At least that's what others using Magnaflow cat and Magnaflow cat back on 4L have told me.

I'm using Magnaflow cat and Dynomax cat back. I like this combination for its quiet performance. Sounds like stock, but performs better and gets better gas mileage.

I used to have Hush Power on my prior Jeep 4L. It was annoyingly all the time. It was loud, droned, and sounded like a can of angry bees. Like some kid's Honda with loud "can of bees" exhaust. That was with stock cat.

Don't mean to bump an old thread but just thought I'd let yall know I went with the Flowmaster super 40 muffler and tailpipe for a total of $160 and after a few months now with it on, I absolutely love it exactly what I was looking for good rumble and good pop. Not too much either.

Of course its a video so the sound is gonna sound a tad worse but it sounds spot in IRL. Only thing I would want would be a better drone sound, but hey its a v6.

Beep, Beep, I'm a Jeep!

FIFY.

And to the OP, this is a free mod. Really sounds bada$$ when you stand on the loud pedal.

The dynomax is surprisingly loud at certain parts of the rev band. At idle it has a nice rumble but move up to around 1500 rpms and it gets pretty loud then quiets back down again up higher in the rev band.

As an older guy that has lost most of his hearing because of loud exhausts and even louder stereo's I can say that the stock exhaust noise level is where I want mine.
In fact I want a silencer on mine.

Lol. How does that old saying go?? "If its too loud you're too old". Im just messing with you. I myself have a header from ebay 6-2-1 design, a spun stainless steel converter, thrush welded, and a custom made 2.5 inch tail pipe.

You are probably referring to the 2.5 inch Dynomax that comes for older model Cherokees. It makes a little more noise then the 2.25 inch Dynomax, but both are pretty quiet except for a nice little growl at idle.

The 2.25 inch Dynomax is for later model Cherokees and it is very quiet IMO, except for a nice little growl at idle.

I have tried them both.
