Who's HFCs should i buy?
 

Okay I've done quite a lot of searching and reading, seems like everyone are going for Berk/stillen/FI HFCs. But I really would like to know what the difference are between them? What would you recommend, would there be a sound difference, difference in performance? I'm just planning on getting HFCs on with stock exhaust. Thanks ppl
:bowrofl:
PS There seems to be ppl saying that FI's HFCs has the lowest probability of giving a CEL light but its' the most expensive!

TWO LETTERS: F. I.

Don't forget to buy the anti-foulers

I got BERK without purchase any extra.No Cel light or whatsoever

get berk, you don't need anti foulers, the adapter is built into the part for the oxygen sensor so you won't get a CEL. just be careful with the install, my mechanic somehow managed to break my oxygen sensor in my header, so just make sure ur careful with removing the bolts, they are very tight but still, be as careful as possible..
