Default Magnaflow too loud... on 96 FJ80

I went to A&A Performance Muffler I had a new cat installed and a Magnaflow Performance Muffler. Super loud I hate it. I went on a trip with the wife this weekend to Pueblo. It was horrid.

What options do I have other than the Magnaflow. We couldn't even hear each other talk.

Call the shop and ask them what they would suggest. It seems common (at least based on threads I've read) for folks to have a resonator or something put in line with the muffler to deaden the sound. I had a Magnaflow on my Durango and love the burble and sound but I also felt that on road trips the drone inside the cabin was tiresome...

There are differant Magnaflow's! Get the large oval one that is packed and the noise will drop to an acceptable level. Droning is tricky to filter out. The 50 series (and up) Flowmaster is another muf that can be acceptable in noise but chose wisely. The biggest issue is how smooth the 1FZ runs. The pulses are very tricky to deaden and if it's the wrong muffler it will sound weird.

I cut the resanator out and added a glass pack in line at the output of the muffler and that helped a lot. I was running a magnflow but beat it up a bit and switched to a Flowmaster 06 series. It's real nice. Not as quiet as stock.

On the Bronco I went with the Hooker Aerochamber based upon this thread. Of course a Ford V8 is a bunch different that a Toyota I6 so the Hooker could be worse. I like the Hooker Aerochamber's sound and it does not seem to drone on and on.

Just call them, they are going to install a FloPro muffler. Anyone familiar with that brand?

That is still a similer three chamber design plus it shortcuts too....I think it will still be noisy.

Magnaflow


Flowmaster 70 series

FloPro is what my exhaust guy used to install - they are very heavy duty. He preferred them to FlowMasters.

In the FloPros's 'truck muffler' line, they have baffled and unbaffled, and if you had a cat converter, my exhaust guy would install the unbaffled, as the cat would somewhat silence the exhaust. For non-cat. equipped trucks, he'd use the baffled one.

Any time you put a 'loud' muffler on a large enclosed vehicle (Suburban, Land Cruiser, etc.) you risk loudness inside the truck. On a pickup truck, this noise resonates to the bad, but on an enclosed vehicle, you get to hear it all.

I have a Flopro on my 40. But it's noisy anyway on the highway so I can't tell the difference

I like the sound of it on the trail when the engine is pulling hard and I can hear the exhaust roaring out
