Welp...follow up...
Matrxx Dude came by today and worked on the car...I had to stay inside and wait on customers so I don't know all the details but this is what I think I know...
He pulled out a 6" aero...still wasn't low enough
He drilled a hole in each of the dust cap and put the 4" aeros back in but cut them shorter to bring the tuning fq up a tad...still not low enough but I'll be damed if it worked...they didn't whistle like I thought they would
He returned everything like it was origionally but with a hole in each dustcap and it appears to be working...so thanks bumpin buick for the suggestion
