Previously, I had the magnaflow exhaust paired with art pipe replica and I didn't get a hiss, rather I got some chirping on decel only around the 1800 rev range.

Interestingly enough, I tightened the bolts even more and it made the rattle worse. Incredibly weird and I'm giving up. Berk HFC are still intact as well. I'll be inspected them again soon and will advise.

Interesting as all I did was go from OE cats to FI High flow and passenger side picked up what is described here as "hiss" after 1k miles, although I've yet to check for a leak.

Highly unlikely there's a leak lol. It's a Z VVEL thing. My Berk HFC are all good and are holding up strong with the many hard miles at the track.

Here's a video of a 1:55 (robbed of a 1:54) at Sonoma Raceway this past weekend. Enjoy!
