Resonated HFCs are the best of both worlds. On the G37 side this is an extremely popular product because its proven over and over and over again to keep away any unwanted rasp/drone but still giving you the added power gains you are looking for. If you are ready to place an order, or have any other questions please give me a call here at the shop!

Thank you, Blake

So what is the difference in having only the resonated CBE, versus having the resonated HFC also?? Meaning besides the minimal HP increase how does it change the sound. I'm assuming to some degree louder.

The resonator in the Cat will perform just like the resonator in the X Pipe. It is designed to be a noise canceling device. It does not hinder performance at all due to it's straight through perforated core design.

Now the resonator in the cat is obviously not as effective as the resonator in the X Pipe. Reason being it is much shorter and the O.D. Overall Diameter is smaller as well.

Now having resonators in the Cats and CBE will smoothen and quiet your exhaust note down.

Thanks, Tony
