I installed a Dynomax 17345 Exhaust System over the winter and just started to drive my Jeep more often. The was a 146 dollar cat back system. It all fit fine no issues, however, the sound is a lot 'Rice Burner" than what I want. I would like a much quieter muffler. Any suggestions? I want a more stock sound.

I have a Banks cat back and it is loud also. Cross it off your list...
-
do you have your cat still on? is it gutted or removed? if the latter then will make it quieter with a proper cat installed.
-
I replaced my cat at the time I put on the Dynomax 17345 Exhaust System I really liked that rebate. To me Its not really that loud and for sure does not sound like its got a fart can on it. Its a deeper rumble.
-
i have a magnaflow straight thru glasspack, it's not loud but i replaced the cat when i installed the muffler and tailpipe (all 2.5'') - it's a little louder than stock but absolutely reasonable and while short shifting it's as quiet as stock, noise goes up past 3000rpm but it's still not too bad. My guess is the cat is probably broken inside.
-
It has the cat and it,s not gutted. I liked it for a day or two then it seemed to get loud. It more of a loud drone sound to me. I need some thing quieter.
-
most quiet one would be a stock or stock-like. Like i said, mine is acceptable but that depends on what you find loud (never use dynomax so i can't compare). Magnaflow is fairly quite imo given the fact that it is a straight thru glasspack.
-
I had the Dynomax cat back as well. I also have a magna flow cat. I got rid of the muffler within months. I went with a Walker "quiet flow" muffler. It was a better choice but not quite stock sounding.
-
Flowmaster makes some fairly quiet stainless steel mufflers these days. My Dad has one on a truck of his.
Quiet mufflers don't come to mind when you think Flowmaster, but I guess the company is trying to make inroads selling after-market exhaust parts to a broader market.

I think I getting close to what I need here! Did the Walker fit directly using the Dynomax pipe from the converter and tailpipe?

Yes, the Walker was a direct fit. Just make sure you get the same diameter and offset inlet/outlet. I will have a look at mine later this evening.
I read that you have a stock cat. I would think that with the stock cat and a Walker Quiet Flow it would be closer to sounding stock than my magnaflow cat/walker muffler.

I had Dynomax, it was too loud,had very loud drone/buzz sound. I went with Banks,it was a little better, not as loud and a bit deeper. The thi6cyng is, the aftermarket exhausts never sound as good on our 4bangers as they do on the 6cyl

Yes! Exactly the sound I'm getting from my Dynomax. It has NO pleasing tone to it. I just want to go back to quiet(er). Interesting, I e-mailed Walker and they still have not responded.

Walker response just arrived!
"Thank you for your inquiry for Dynomax Exhaust. We appreciate your interest in our products. I am sorry but we do not have an Quietflow muffler that will fit in the place of the 17731 Super Turbo muffler that was in the 17345 kit. The only thing I can recommend would be to return the kit under the 90 day safe and sound guarantee to the original retailer and then put on an OEM style system listed below."
I was not aware that Walker owns Dynomax....or vis-versa.

neither, they're both Tenneco brands along with a bunch of others. Walker is the OEM replacement, Dynomax is the performance division

I asked if they had anything quieter than the Dynomax, and here is the response:
"The closest I can come up with by size will be an 18113. It has an 18" body and 26" overall length. The 17731 from the kit is only 18.5" overall length and a 14" body. The inlet on both is a 2.25" offset and the outlet is a 2.25" centered.
Sorry we don't have anything closer. "
When I get to the Jeep I will measure and see if it would fit. Seems a little big to me.

That would not fit on mine would put the Muffler part way over the Differential.

I'm sure there are some out there that would fit, in my case I upgraded to 2.5'' starting with the cat, for muffler I used a Magnaflow 14226 (8''x5'' oval, center/offset 2.5''/2.5'' inlet/outlet reversible, 14'' body, 20'' overall length) - it's a polished stainless straight thru glasspack
you could use 14225 which is the same as the one above only with 2.25''/2.25'' inlet/outlet (or slide the cat further up with 14225 to gain an inch or so if needed and the same between the cat and muffler) or the 14362 which is 17'' overall length, 4''x9'' oval and 11'' body with 2.25'' inlet/outlet you might need to add an extension pipe between the muffler and the cat with 14362 (or maybe just use a band clamp or 2). The smaller they are the louder they are though so 14225 would be the better one.

I believe I bought my Walker Quiet flow at Lee Auto parts. It was the same dimensions as the Dynomax.

I climbed under the Jeep. The part number is 21200. Here is a link to the cheapest I have seen:http://www.summitracing.com/parts/WLK-21200/Application/?query=Engine+Size|2.5L%2f150 (http://www.summitracing.com/parts/WLK-21200/Application/?query=Engine+Size|2.5L%2f150)

I have the Cherry Bomb Turbo muffler on my 2001 TJ Wrangler. A little louder than stock but not obnoxious at all. It is an offset design, not a straight-through. I am very happy with it.

i thought straight thru means no baffles (i could be wrong though), mine has an internal bend also as it's offset like the stock is but it's just a pipe with holes.

I realize this thread is a bit dated and the OP might have solved his issue by this time, but I've ran a Magnaflow XL series on my rig with a stock tailpipe config for about 4-5 years now and am pretty happy with it. It's gotten louder as the packing has gotten older, but it has a pleasant tone and doesn't sound ricer at all. It's stainless and has 2.25" in/outs, I dig it :thumbsup:
-
I believe threads never die! Still running the same Dynomax and still not happy. The Jeep is now at the cabin so I will have to wait till the Nov timeframe for my up-grade. Still looking, still listening to Jeep that I come across. So far, I'm liking the Summit link. 71 bucks is about what I paid for the entire Dynomax system.
