Cat/Muffler/Tailpipe recommendations

So in 6 years I've run a 3rd Walker cat into the ground (it's shot and sounds like a pebble in a tin can) and am looking to replace the Walker exhaust too since it has a hole in the side of the pipe.

I'm tired of replacing the Walker products so I thought I'd post this since there isn't much in the way of threads and the Exhaust review section has mainly throaty growling exhaust systems.

I'm not looking for the a serious sound upgrade. I don't want to have to listen to growls and pops during my commute as a DD.

What i want is a nice confident rumble, better HP but most importantly durability in a cat, muffler, tailpipe combo.

Cost is limited to ~$200.

Thanks!

I got a magnaflow cat and heartthrob complete exhaust off of Jc Whitney for around $200. I've been running it for about a year with no problems. You will need an extra 6" of pipe, being the cat is shorter than stock.

I got a Magnaflow cat as well. It was $73 from Summit Racing. I live near a store so no shipping. I already had a Flowmaster and my exhaust was falling off so I took it to an exhaust shop and had them run the pipes the way I wanted it and weld in the new cat and old Flowmaster. I spent $225 for new pipes from the manifold to the Flowmaster. I also went ahead and bought a new exhaust manifold for $72 off eBay. Total I spent $370 for a new exhuast. It's a lot quieter now and I don't hear it banging around when I'm in the woods.

I went with a stock oval can, and stock cat, and I have the nice meaty rumble. I did it by putting a turn-down or a turn-out directly on the muffler pointing down at the road. The sound bounces off the road and vibrates the floorboards, sounds kinda like a semi taking off.

What year is your jeep? Mine is an 89 and i did away with all of the emission things, i picked up a flowmaster muffler off of a 94 mustang from a junkyard for 10 bucks! I pretty much ran a new exhaust myself(16) from the front of the cat all the way back. Its not too loud for me, but i am also kid so i made a mistake, i picked up all of the right adapters and pipe from advanced auto for around 30 bucks and when i cut off the turn down from the old muffler, i cut it too short and i couldn't find a big enough adapter and just ran it with no tailpipe, straight out of the muffler. Like i said, its not too loud for me but could have a different effect on you, good luck though!

It's a '91. Gotta few more years before I reach the golden years of no inspections.

$200 for both the exhaust and and cat may be hard to find unless your getting a used one.

For the muffler I have used this brand fairly inxpensive(I had it on a 98 TJ 4.0 L):
http://www.ebay.com/itm/Dynomax-Supe...ea6435&vxp=mtr

Next year I plan on redoing my exhaust from the headers to the back and for the exhaust I plan on getting that one.

I've been looking around and I may have to butter up to the wife to increase my budge by a few dollars. $200 will give me another Walker combo and frustration in 2 years.

The Dynomax is at the surface with respect to a balance between performance, sound cost.

I went with a Dynomax/Magnaflo combo. Slightly better fuel economy and power although I think that's starting to diminish. Those benefits are offset by the noise though.

The noise doesn't sound as pleasant at speed as I had hoped. I can live with it though. At 3,000+ RPM the 2.5L starts to growl and it seems to keep the neighboring cars from tailgating.
