OK guys got my Berks HFC's last week and after inspecting them I noticed that inside the bung for the O2 sensors there are UM I guess what you would call springs?? I looks like metal sping shavings.. Hard to explain I guess with out seeing them. But is this normal so these do not throw a CEL..
Thanx Guys

 

Installed on Saturday. I love the sound I little louder but good. I was wondering if everyone else with HFC's ahd that metalic sound when you go WOT. Almost sounds like an exhaust leak but its not..

 

Kinda like headers on a big block?

 

Yea I guess like in tinny sound.. And can someone tell me why our exhaust is SO SMALL, GOD looks like Civic exhaust.. LOL
