Low Pitch Muffler.
I’ve been searching for a low deep rumble muffler that wasn’t crackly or poppy. And this definitely delivers. I’ve had the 40, 44 and super 10 from flowmaster. It’s the right pitch but not quite as loud as the super 10. I’ll be removing the resonators from ‘14 1500 to get the missing volume but all in all, it’s exactly the tone I was looking for.

Magnaflow 6” muffler, 3 “ inlet and outlet.
Just got this muffler for my 2003 RAM 1500 5.7. Personally I really like it, it’s not obnoxious loud but it has a nice low grumble to it. If you want obnoxious loud get a Flowmaster but if you want a nice sounding deep tone and don’t want to wake up the neighborhood this is what I would recommend.

Great Muffler
I love this muffler! Welded a 90 degree angle onto the end. Welded it in about 30 minutes. Very loud!

More torque,More power!
Great sounding exhaust, increase in torque and speed. Need to add an air kit to lean it out a bit.

My OEM Catalytic Converter shipped quickly and on time. Althought I had a shop installed it, there were no issues or concerns with the direct fit of this converter. Price was good as well.

Good muffler
Muffler sounds good. While not drowning on the highway I did a muffler change while keeping 3 cats but removed resonator and it sound well.

Christmas present
Got this as a Christmas present in 23 finally put it on end of June 24. I deleted the old muffler all the way to the tailpipe and resonator. This glass pack sits right under the bed of my truck and gives an amazing sound to the exhaust note. Not loud enough to wake the neighbors, but perfect if you just want to enjoy the sound of your engine
