Which muffler?

Whatever it is, I don't want it to be crazy loud and I don't want too much interior noise. This Jeep has no real soundproofing.

I have a 50 series just a step louder than the 70. It's plenty loud for a daily driver. I've been considering getting something quieter.

From your list I would go with the Magnaflow. Dynomax has some decent sounding mufflers that are pretty cheap.

I'll take a look and see what Dynomax has to offer.
Wow, I'm likin' the dynomax VT. It has a little valve that when the engine isn't under load, closes and directs the exhaust through more baffles, quieting it down. But the valve opens under load and gives the engine some throat.

Leave the Fmasters for the kids.
I still have a knock off FM on my Ram and I hate it. The Cherk has a nice Magna 3" muffler and cat. It's quiet but has a nice snarl.

The VT is probably not going to be your best choice for a mild sounding muffler. I imagine it sounds a lot like a turbo or a glass pack. It will probably work great at first then soot will build up on it and the valve will stick open after a while and you'll hate it. It looks like a good idea but I would stick with a muffler that doesn't have any moving parts.

The PO put a Cherry Bomb on mine. It's not too loud on the inside. I'm not sure how loud it is on the outside. It has a nice rumble.

I love Borla. I have had them on a Ford EFI V-6, a 5.0HO 302, and, as of today, on my Cherokee. My Cherokee with long tube headers and no cat is a little louder than stock but much deeper. Borla ProXS are also straight through design. If you want it to sound like a muscle car, get the Flowmasters. If you want it to sound deep and mellow but have the flow of a straight through muffler, I recommend a Borla.

This is the muffler I have on my Cherokee now and I love it.

Wow, this is an old thread. I started this when I was a sophomore in high school.

I went with the Magnaflow, by the way. I had it on there for a couple of years until I finished high school. I removed it and replaced it with a Walker Quiet-Flow SS stock-type muffler before I made the 980 mile drive out to Kansas for my freshmen year in college because I didn't want to listen to "BBBBRRRRAAAAAAAAAAAAA" the whole way there. Now I'm graduated and the Walker is still on there.

Best decision I ever made.

It was nice listening to the rumble of that 360 while I was a punk in high school, but it got really old really fast on the highway. I decided I'd rather be able to hear Carly Simon on the radio.

^oh, you putz!

I love my glasspack. Sounds damn good to me. Don't like listening to the radio much when I drive. I'd rather listen to my engine and noises around me.

Man, I cant stand those flowmaster's. Don't know why, but I think they sound stupid. I'd go with magnaflow if I need an actual muffler that still had some good sound...but for me. Well, none of my vehicles have a real muffler anymore.

I adopted this philosophy:

1. I don't need to hear what is under my hood to know what is under there. I built it on a stand and put it there with my own two hands. I might as well not hear it at all. I can still hear it if I listen hard enough.

2. I'd rather sneak up on people in dead silence and suck their doors off without them suspecting anything. A loud exhaust makes them suspicious. I can be more of a sleeper if I'm quiet.

3. So long as I don't care about hearing my engine, the only other reason I'd want any kind of noise is because I care about what other people think of my car when they hear it. Except.....I stopping giving a sh&t what people think a long time ago. People are stupid.

4. I like being different. Most people who have old cars have loud exhausts on them. I am different by having old cars you can barely hear at all. I like that.

5. I'll still sometimes unbolt the cutout and drive around open pipes when I feel like it. It's fun sometimes. The neighbors love it. But that's ok: their yappy little dog sh#t on my lawn last night, so screw them.

So yea, I'm pretty much an old man.

Old Ironsides has had Turbo mufflers as long as I can remember. It's got dual exhausts, doesn't sound loud or wild, but with the cam and 401 It is a nice, familiar rhythmic rumble I've known forever.

I am your guy for this...

My friends at the muffler shop talked me into the flowmaster 50 series saying it had just a little grumble, but wasn't too loud.

However, it's still too loud. They forgot that these jeeps are always pulling. When you have your foot on the gas there is a nice somewhat subtle growl. The problem is our foot is always on the gas.

With this said, I just did over 500 miles on the highway in the Jeep and it was better than I thought.

If it were me I would go with just a standard off the shelf stock style muffler.

here's a write up I did with a video so you can hear the flowmaster 50 at idle. I didn't record it when giving it gas.

just my 2 cents

People tend to forget or overlook body shape when designing exhaust systems. Vans and wagons usually have a resonator somewhere in the exhaust system, typically toward the rear, to kill the drone or boom that those "big box" bodies are susceptible to. Muffler shops may not bother to include one, or the customer may not go for the upsell, so there can be more boom than an original system even if the volume outside the vehicle isn't excessive.

In other words, there's more to exhaust sound than which muffler you choose, and a wagon will be a whole lot pickier about design and components than a pickup truck will.

I hate to say it this way, but...muffler shop employees are not engineers. They're typically no better trained in either acoustics or performance theory than we are. They sell Flowmaster because 1) it's readily available, and 2) it's a brand name that customers recognize. Both of those are huge advantages when your business depends on getting product in and customers out as fast as possible.

Accordingly, customers ask for Flowmaster because muffler shops recommend it. It's a loop.

I really don't mean to be so cynical all the time, but...there it is. A name embroidered on a shirt does not an expert make.

You might be able to make lemonade yet. Is there a straight section of tubing in your system that will accommodate a resonator? Adding even a basic glasspack muffler to your system will do a lot to soften the tone and kill the booming, droning sound Flowmasters are famous for.


My favorite for most applications remains the Hooker Aerochamber. That design seems to produce a smoother, more restrained tone without the popping/blatting sound that Flowmaster mufflers are known for. However, they are more expensive (because they cost more to make) and are not stocked on every corner, so a lot of folks are not even aware of their existence.
