Berk HFC stock exhaust

AnanZ

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!!
