What would you put on your KK if you needed a muffler, tail pipe, and resonator?

The options in the poll seem to be the available ones. I would totally go with a Magnaflow kit, but they stopped making them unfortunately. MBRP makes a good performance model for the KJ but they don’t have a KK kit. I am also leaving out Flowmaster since they are too loud for me. The characteristics I want are:

Stainless steel - I want it to last a good long time
Not too loud - because my wife deals with migraines that make her sound sensitive
Reasonable Cost - Willing to pay for a good system but don’t have an unlimited bank account
Performance - a few extra HP would be nice but I consider this optional compared to the above criteria.

The Walker is the cheapest at under $200. It also is probably the quietest because it is not going for performance. But because it is made of aluminized steel, not stainless, I would be doing this again in a couple of years.

The Dynomax is middle of the road in terms of cost, about twice the Walker, let’s say $400. It is stainless supposedly, but I am guessing quality and performance are also middle of the road. Seems a bit loud in YouTube videos.

The Gibson is pretty expensive at about $600. The quality is there with a lifetime warranty on stainless components. The performance of its thru-flow design adds 5-15 HP or so they claim. The trade off is the Gibson seems loud to me in the videos I watched. Also, the chrome exhaust tip protrudes about 4” behind and below the bumper, which is not ideal for off road clearance.

Mopar. Perfect fit, great quality, and quiet. My original one lasted 10 years. But it’s $1000!!! The high cost seems prohibitive.

Ok, what would you do? I am also interested in other options that are not on this list. Let me know the pros and cons of your experiences with different brands. And thanks in advance for your thoughts.

I voted Dynomax simply due to the fact that the Walkers will rust out sooner
Im running walkers on the 03 and 04 both now , quiet but only last 2-3 years at most I would say
Gibson sounds great on V8s , never heard a V6 running one but yes expensive for sure

Sorry I replied tonight to not-the-latest post on your exhaust issue. I have the stainless Gibson - GIB-617205. I am (still LOL) the 1 and only review of it on Summit: https://www.summitracing.com/parts/gib-617205

First off, it is not the quietest. Slightly louder than stock for sure. I have a stainless Gibson on my S-10 (also a V6) and it sounded the exact same as stock. Can’t lie, I was surprised it was louder on the Jeep. Plus side is the S-10 exhaust is still doing fine at about ~9 years old on there.

Quality wise it’s great I’ve had no issues since putting it on 5 years ago.
I see it’s $425 on Summit right now legit 2/3 of what I paid. So price is good.

The too-long length of piping is not a big deal just an annoying extra step. Funny I finally cut it off and put on the stainless tip this past January. Quick and easy cut w sawzil. Pics of pipe sticking out attached. ***let me know if you want interior and exterior videos happy take some for you!

Funny enough, I ended up going with an exhuast system not on the above list!

https://www.brexhaust.com/

BRExhaust is a subsidiary of Magnaflow, but they do high quality OEM replacement exhaust systems rather than the performance systems I was looking at before. Although the construction is aluminized steel, the interior bits of the muffler are stainless, and it comes with a 2 year warranty. These systems are meant to be as quiet as stock, which I like. They are made in Kentucky by American workers, shipping was free, and the price was $226. Not too bad. I’ll let you know how the install goes.

Nice! Glad you found one. That's a good price too. Hopefully that steel construction holds up past the 2-year warranty. Glad to hear it's stock-level sound since that's what you were looking for.

@runfor5, thanks for the detailed post above on the Gibson. Although I didn’t go that route (because of the sound volume), I know that kind of information will help someone else down the line who looks at this thread. :cool:

Have a Flowmaster and it’s quiet, no drone or anything if that helps

Isn't it great with all the salt and chemicals that Pa. puts on the roads what the effects are to our vehicles!

Life happens, and my new exhaust system continues to sit in a box in the basement. I will hopefully have time to install it in a few weeks time. Meanwhile, Jeepy isn’t too loud as the main muffler on the old system is still mostly intact (for now).
