Contact CVFab

“There are two defoulers in the box for the two lower o2 sensor holes on the cats themselves. It’s standard for any aftermarket high-flow downpipes from any brand.”

Did any of you guys notice a loud rattling noise near the end of the mufflers when installing these CVFAB downpipes. I noticed immediately afterwards. Never had this noise before the downpipes. It's when I start up and reverse and while at low rpm's at slower speeds??

Check the exhaust pipe rear end support hook. The sound caused by the friction between the hook and the plastic.

so check the rear end part of the exhaust where it's connected to the hangar. I did notice the drivers side exhaust was a bit more loose then before the DP.

Hangars should not be touching. I had the same problems when the idiots installed mine. It was very annoying.

Not touching the bolt. It’s just how the picture is (point of view). Hangar can go anywhere on it, just not touching where it angles down..

I crawled under there the other day. I see what you mean. Doesn't even come close to touching. I pretty much got the rattle to go away. Thanks again
