I initially had the Berk HFC'S and was advised to switch when I went Force induction to avoid burning them out due to increased EGT's...since I have the Berk CBE I spoke to Brian at Berk and got his opinion where he recommended going with the Berk Resonated TP's.....Let me just say I wished I would've got these from the get go....nice and clean...no drone or rasp...just a tad more louder and aggressive sound with the Resonated TP'S vs. the HFC's. Again this could be due to being paired with the Berk exhaust...I'm not sure how it would be with any other CBE out there...
I don't have too many Vids of my car but I posted one in another thread when I hit the drag strip a few months ago....this should give u an idea of what it sounds like...
OFFICIAL Boosted Video Thread...Please you're my only hope
