Well the theory is that the extra exhaust being able to flow through the HFC/TP's into the xpipe is y the noise is present and you will not hear it with the stock cats.
Someone mentioned using heat wrap/thermowrap on the xpipe and it limited/removed the noise...but thats rumor, the person had heard that from another person :/
