Carven progressive muffler gets louder and louder. After two months, got so loud I removed it. Almost as loud as my neighbors muffler delete.
There is some drone. In 4 cylinder mode very annoying. Final straw was a 100 mile trip with a lot of uphill driving. Great when first installed,
to bad it...
Eliminates 90-95% when you are running 8 cylinders. Installs like instructions on a 4WD.
2WD must be installed farther toward the front, no room for full adjustment if needed.
Absolutely use high temp silicone on joints.
Installed the Carven Progressive on my truck. Great fit and quality. After a few months it got really loud. Almost the same as the muffler delete. Sounds great but it is always loud. Finally had to remove it. Also, it is really annoying when it is running in 4 cylinders. 2019 Ram 1500 Classic.
