2023 f150 whipple 3.0 supercharged fx4 lariat with the borla atak exhaust. I found it to be too loud so we added a 3” magnaflow muffler to quiet it down. Before and after vid
It’s a magnaflow 3” oval muffler, offset inlet and outlet. Not a straight through design. You can hear it in-cab in another video I just posted of a 0-100 run.
