The HFC will sound better than stock but the CBE will give it the best sound out of all mods but it is also the most expensive one. Also IMO HFC will degrade somewhat quickly and start to sound raspy and you will have to replace them again or put up with the sound where the CBE wont do that. Right now the ERZ are the least expensive HFC but we are kinda waiting for a certain amount of miles on all HFCs to see how they fare over time, as if they wear out.

Now that I have finally got my ERZ HFCs on, I am actually thinking about putting the stock cats back on as I am kinda on the line about the volume and some raspyness. The FI CBE by itself sounded awesome.

I know huh! They do have a bit of rasp to them at time, then at other times they sound ok. But I can feel the difference they make so they wont come off till and only maybe, when I do the final drive upgrade. Need that Army money they owe me for the stop loss so I can do the final drive and lsd at once. Im off to NJ tomorrow for 3 weeks. You gonna be gone when I get back? Have to give me a call if so, to thank you for helping me here.
