Ohh alright, i like the sound of the fast intentions im just worried itll be too loud, the z is my daily driver so i dnt want to come home late at nite and wake the neighborhood up lol.

Get the 18" resonators if you're worried about volume.
And tbh, your biggest concern should be waking up others in your house, since they'll hear it much louder than neighbors will. You'd be fine as long as you dont go heavy on the pedal and keep it at low rpms.

True, and worst case if it is too loud i can take the hfc's off, does the deep sound carry even at low rpm?

Hows the fitment for the fast intentions, are the pipes in the back at a different height, kinda like the ark exhaust? Its hard to tell from pics but it looks about the same height. Would i have any drone with the berk high flow cats pair with the fast intentions 18" resonators?

hks by far rocks the one and only,great fit, great sound no other exhaust sounds like it you will love it

I have Berk HFC and CBE. looks good sounds good fits good. Bauble hangs down at the flange just a hair lower than stock.

Fun choices!!!

I love the raw sound of the hks but im trying to stay around a grand and trying to stay quietishh, how loud is the berk set up on a scale of 1-10 or compared to the 18" resonated fast intentions?

Berks are quiet, maybe 93-95db. They sound good when paired with their HFC's. You can find 18" FI exhaust on the forums for about $1100, I would choose that over the Berks. Hard to go wrong with our exhaust options. It's surprising how different the car can sound.

fast intentions non res, with berg or fi hfc?
 

which hfc do you guys recommend berk for fast intentions? with my cbe non res i want no rasp

If you want no rasp at all than go with our Resonated High Flow Cats. They are specifically designed to cut out rasp and cut down on interior noise resonance without hindering the performance.

Thanks, Tony

no cell correct

Absolutely not! NO CEL with any of our products as long as they are installed correctly.

Thanks, Tony

I have FI NR HFC and do not have rasp. Just pure joyful sound.

FI non resonated CBE
