Berk HFC stock exhaust
 

Hey guys, i was just wondering if anyone has this setup of Berk HFC with stock exhaust. I have a couple of questions:

1. How much louder than stock can you say it is? like when driving around, is it noticeable and can people tell that its not stock? can you hear it in the cabin? is it deep?

2. Does it pop? like when you rev it on idle or when you down shift, does the exhaust pop/burble? And how often? I know most people hate this and try avoid it. But i like the popping sound.

Thanks!!

It sounds like ****. You will want more.

I had the berk HFCs first but wanted more so got the berk cat back. Sounded very nice but I hated the rasp/drone from 2-3k rpm.

Idle and cold start is alot better, deeper, can tell difference in cabin. Sounds amazing with Stillen gen3 up to 4k, after 4k it's a different animal, loud/ I'm getting a lot of rasp. The downshifts sound alot better, little increase in burble. Very happy, but still studying my raspy ness.

I had Berk HFC on my 350Z HR and there was noticeable rasp between 2K and 3K RPMs. I switched to FI non-resonated test pipes and the sound improved drastically. The exhaust note was deeper, louder, and the rasp, from what I can remember, disappeared.
