Berk HFC or Berk Test Pipes?

^^yes i do. u will definitely feel a difference. makes the car sound mean as well. DannyGT did not like the rasp, so he got resonated test pipes from GTM. i got testpipes because they provide more power (slightly over HFCs), they were cheaper...and no1 else had them at the time. The rasp is not bad at all (my opinion). its only from 2500-2800 rpm under accleration. i do mostly highway driving 70-85 mph...and i cant hear any rasp/drone while driving. i think it really brings the car to life. if u wanna stay legal and have great performance...go for the HFCs. if u want a more raw sound...do test pipes. if u dont want that rasp..then go for the resonated! good luck and post some results!

We have seen some awesome gains with our HFC's. When we tested our HFC's Vs. Test pipes we found that the test pipes only produced about 2 horsepower more than the HFC's. Here is a clip of DDM's car just in case your worried about the sound or the exhaust being to raspy.
