So I installed the Spectre hi flow cone filter into the max today with a spectre MAF adaptor. After driving around didn't really hear the growl as to other intakes.. Maybe around 5000-6000 rpms. Would the JWT pop charger be good for a better deep growling sound or a mid pipe at lower ranges maybe around 2000-4000 rpms.

P.S I will be installing headers in the future but for now just stuck with this.

 

Straight pipe raises sound levels, if that's what you're into. JWT/Stillen POP's are fairly quiet actually since they retain the OEM Helmholtz resonator, as does your set-up.

And as with all intakes, they only growl under WOT or near WOT situations.
