Installed Berk's HFC's today
 

Before I comment on the instructions or lack of is there a sticky for this that I did not see?

If not I will provide my feedback/lesson learned!

is that 230hp to the wheels?

Yes and before the HFC's.

Nice exhaust and HFC

How are the sounds?

Are they much louder than stock?

Any drone or anything???

:JAMIN:

Day 1 of driving and it is louder and there is drone at 2K...I am hoping it gets quieter as they break in or this might not work.

you a coupe? at or 6mt?

Coupe 5AT

I hope the drone dies out because, HFC's were supposed to be my next mod. As you can see by my SIG, aside from headers, there's nothing else I can add for now. Keep us posted please.

I have stock exhaust, and Berk HFCs.. The drone dies down when you break the HFCs in.. I have some as well..

How long did your break in period take and what was the noise reduction when you said the noise died down?

I bought mine used, and all I hear now is a nice grumble of the air going through. No drone..

Not exactly sure how many miles it takes to wear them in.. But mine certainly don't drone.

Maybe there is hope!
