VN900 Custom New Pipes No popping sound

So I just had my Cobra Swept pipes installed with no FI kit. I hear a pop in the exhaust on deceleration now which my mechanic told me I might hear. I don't want to invest in a FI right now unless I need to. I thought I read somewhere that there is a fix by modifying something in the airbox? Any help is appreciated.

do a search on "marbling" the intake, there should be lots of info on the process including pictures
