I was wondering if HFC's would cause any drone at all? I have the X02 now, and the drone is very annoying. I'm looking to go back to stock + HFC's. Probably Berks, because theyre having a sale right now

 

I've heard HFC's and stock exhaust before. It wont drone like your XO2. I remember it just sounding like a louder Stock exhaust. But If you cut the resonator on the midpipe then you will be droning again.

 

i've heard Berk's HFC's drone pretty bad

 

No drone that I have heard with my Berk HFC's, MotorDyne XYZ and stock exhaust. Just a bit deeper and louder.

 

Berks on stock exhaust?? I have my stock + HR Y-Pipe waiting to be put on

 

No droning when I had my F.I. HFC's + stock exhaust. Unless Berk HFC's are really crappy, you shouldnt drone with those either.

 

Same here.

 

^ Your post count makes me feel like such a noob

 

HFC's or test pipes will only increase the drone on the X02 and to top it off, you'll add rasp. You'll need to add a resonated x-pipe in place of the X02 resonators. My drone is gone and I can barely hear it cruising down the freeway.

 

I'm gonna take the X02 off next week....
haha yeah i know. it was very short lived. definitely sounds nice for the price, but its just not for me. i miss the stock tone lol

and thanks for your help, guys. Unless FI HFC's pop up in the classified soon, I'm probably gonna go with Berks

 

I had Berks with Stock and no drone at all

 

Same here. Love my Berks!

 

no drone here, coupe midpipe and original 05 sedan muffler.

 

Sound clip?
