The question it's Berk HFC or FIHFC?? ortest piepes?
tks,
Test pipes will be louder then HFCs and sound raspy. But it gains you more power slightly over HFCs. Another thing keep in mind is both HFC and TP are street illegal. But normally you'd be fine and pass the inspection. I had FI HFCs never had any trouble. They are more expensive then Berk's but you will get what you paid for.
