Hey, I have a 2007 G35 sedan. I have installed a Takeda intake, Stillen crank shaft pulley and now just installed Invidia q300 cat back exhaust. Thinking about installing hi flow cats. Any suggestions on what would be best for my set up so far? Fast Intentions? Ark Performance?

Thanks

 

YouTube for General idea sound clips.
Search for the HFC opinions.

 

I spent the $$ for Berks HFCs they didn't last a year! Loving the sound of my HKS exhaust with the sound of HFCs I gave Fast Intentions a try, that was two year ago...still loving the sound!
Come on Jerseytaylor, exhaust sound is only as good as the Wallmart recorders used! Only way to really hear any system is in person at meets or a friends G35.

Everyone knows most kids are just running knockoff exhausts now. Ha
No use leaving the house for that lol

 

I have Fast intention on mine. here is a video of the full Fast intention sound w/ the SC. exhaust and HFC.
