Berk Full Sport Exhaust vs HPF Resonated

Hi Guys,

I've searched exhaust threads and listened to sound clips here and have narrowed down my exhaust decision to Berk Full Street or Full Resonated HPF. I have catless AR downpipes. My goal is to have a powerful sounding exhaust without drone.

I've not found a comparison between these 2 systems and would appreciate input. I know this will be a catless system when complete.

Thanks,

John

Berk Street & AR DPs:



HPF Exhaust (driving vid starts at 2:45):



Berk is a smaller diameter of piping. HPF full exhaust is 3.5". Berk is 2.5" with 3" resonator(s), and is also cheaper in price compared to HPF. HPF will most likely be louder given the diameter size..how much louder not sure. I haven't heard the HPF full exhaust in person before. I plan on changing my N55 midpipes for berk, because they seem to be more tolerable. As to the sound/maximum loudness you are looking for, I'm not sure of
