Best AMC 360 exhaust for top down!

I have a Jeep CJ5 AMC 360, stock manifolds, true dual pipes with glass packs, dumping after the rear axle and turned out to the sides.

Now, I like a loud exhaust...but these glass packs just sound like crap. I was interested in some Flowmaster 40's as I've had them on a Chevy 350 TBI Suburban. The Suburban had a way to block out the noise when needed. My CJ5 is top down about 90% of the time. I can't even hear my 35x15.50x15 bias super swamper tires rumbling along. I have researched the Flowmaster Super 50's because of the mild noise. I'm just worried the 50's are going to be to quiet. I like the aggressive idle, mild cruising, and aggressive WOT.

I've just been bouncing around between flowmaster 40, 44, 50, etc.

I use this jeep around town on nice days and plan on more wheeling in the future once she is more reliable. The problem is dealing with these glass packs daily, is very obnoxious. I feel it down grades the majestic AMC 360.

Anyone with experience or video etc.

Thanks.

I don't have a video but I do have some first-hand experience.

First things first: I'm really diggin' your Jeep. The axles may be a bit wide for me personally but the whole package is just bad a$$.

Having said that, I absolutely loathe Flowmasters but that's just a personal opinion. I'm a pretty big fan of Hooker Aero-Chambers and Dyno-Max Super Turbos. Either way, an H-pipe will definitely take some of the bite out of a snotty muffler.

I had a set of Flowmasters on my Hemi pickup and you could hear me a mile away, swapped them out for a set of Magnaflows and they are so much better, but the H-pipe is a great suggestion too.

I had the same concerns as you did and I went with the Magna Flows on my SBC350 after talking to the guys at the muffler shop. I was leaning towards the Flow master 50 series and was talked into the magna flows. I know it's all personal opinion but I think it sounds great. It is true duals, 2-1/4" pipe. It is mild enough to not be irritating but puts out a sound that people definitely know you have something under the hood. When you step on the skinny peddle it will get aggressive as you mentioned. Hope this helps.

x2 on the SpinTech mufflers, for sound and the ability to take a beating as well for those of us who wheel.

Which MagnaFlows?

I like the Jeep, what kind of wheels are those?

Thank you! I'm debating on the tires, 15.50 is crazy wide. I plan on doing an H pipe when I change the mufflers out.

I'll look into this. I'm worried the magna flows won't hold up as well. Do you have a video?

If you want mufflers that are built much more stout than Flowmasters, or Magna-Flows, check out Flo-Pro Max mufflers.

They are a little pricier, but once you compare them you'll understand why. Plus, they are built in the USA.

My pleasure.

I have a fairly moderate cam, and I don't like a loud exhaust, so my single tail-pipe system suits me perfectly. YMMV.

Smooth as a baby's butt, lol. That's pretty quiet for a straight-through muffler. Good choice!

Clean Jeep!

I like the sound of your Jeep! I feel it's a tad quiet for me, which is what I'm worried about with the flow master 50's

I did look up the Dynomax exhaust, and put them on my list!

I'm having a hard time uploading the video it took last night. Here is a pic of the mufflers.
