Anyone running an axleback and HFC's only? I feel like it would rasp really bad but I have found some youtube videos that show it is really deep? Is the camera being deceiving and not picking up rasp or does it really not rasp/hiss? Someone chime in. Thanks

 

I'm not sure what sound exactly you're listening for but here is my setup, Berk HFC and MeganRacing axelback (stillen gen3 intake as well).

 

What I am looking for is when you change to HFC or test pipes it can create a rasp because the rest of the piping is stock but with the HFC/TP there is more air coming into the exhaust. Sounds clean on yours don't hear any rasp

 

I know someone with an OEM setup with resonator delete that is raspy. It doesn't sound that bad to me, but he doesn't like it.

This setup with the axleback + HFC is not raspy at all, at least IMO. Loud, but not raspy.

Also, anyone know what setup that grey G37 was running? His youtube comment says he's on Eibachs - is he running spacers?

 

< HFC (Berk) & Axle Back (Tanabe) installed and its deep and moderately loud but not raspy. It has a very slight kst or hiss sound and a very slight rumble at the end when letting off the gas. Love it

It actually got a little quieter when i installed Injen Long Tube CAIs
