Yes that’s why I went to the flowmaster FX I couldn’t get it in a Magnaflow. I think they are the same, flowmaster copied them perfectly from what I can tell.

No drone?

No drone with the 3.5” flowmaster FX or any of the other vehicles I have used the magnaflow turbo mufflers on. The chambered flowmasters drone like crazy! They make a stock engine loud but if you have a built engine it just makes too much obnoxious noise.

Single 3” in and out. Lots of trucks fit the offset design easier. The larger the muffler the better they muffle. I have dual 2.25” round small magnaflow on my Yukon and it’s obnoxious. No drone but some crackle. Longbtube headers no cats and dual 2.25 true duals. The 3” XLs on my 2500 6.0 are about a 60% larger muffler vs the 2.2.5” ones. I think the XL is like 32” long or something

Just got my parts to quiet down the Dynomax 17553. I will try to do before and after videos to post.

I don’t normally use x pipes I prefer the sound of true duals. The x pipe is worth a few HP but I prefer the sound without.

Is that a mini muffler and a turn down?

Sounds louder on the video but a little quieter in the truck.

Resonators and down pipe, really loud when towing the camper. I cant figure how to upload the videos, but its not much better.
