I am currently running Tommys free flow , I have tried running a home made free flow mod which resulted a drone attached to vibration that I could feel under my feet, 2 days of that crap was just punishment ,so back to tommys ffe and a few ducky's to parts pak for a another oem replacement

-can anyone say that the ffe with thru hull ,has a drone and vibration
-I am trying to get the performance of a free flow , with out the noise
- has anyone been able to come up with better idea than Tommy (no offense Tommy)
