If you want that noise gone on the Ace kit, then add that K&N pancake filter (RX-4130-1) on there and it will be next to gone also, at the expense of some power and needing to remove and reinstall the kit for install and cleaning.

This noise was a non issue on my Gen 1 kits because I sent every kit with that K&N filter and everyone used it and everyone was very happy. Up until 600whp became the new norm and everyone wanted to run just a turboguard to get there
