With the HFCs you wouldn't have to take off your nismo exhaust. The HFCs will have a less "rapsy" tone. There high performance so you get more HP and make the car sound a lot better with the exhaust system that you have.
With the test pipes they add a little more HP then the HFCs, and is louder too. They release the most power from your engine by completely eliminating the catalytic converter. Im sure you don't have to take off your exhaust with test pipes either. So you can't go wrong with both.
Still need my ERZ HFCs sold ASAP
