I have the FI Resonated HFC's and FI 18" Resonated CBE. A friend of mine has only the FI 18" Resonated CBE with stock Cats. There is very little difference in sound between the two Z's side by side, just slightly louder on mine... No rasp on either Z...

hfc/test pipes will always make your car louder then stock cats. my exhaust was almost dead silent before and now my exhaust isnat a perfect tone.

Will definitely be louder in any scenario, not quieter.
