Stillen VS. BERK HFC

ZPhycho · 08-26-2010, 11:14 PM

I was doing research on here and on both of their websites and couldn't find a clear differeance other than right now the stillens are about 20 bucks cheaper, so my question is whats the differance between the two and I noticed that most on here are going with the berks why?

Thanks

HP wise there's really no difference the good thing about the berk's that the stillen does not have is the extended O2 sensor.. this helps prevent CEL's due to higher flow of exhaust fumes.

Stillen will probably give you the extended anti-fouler for free....just ask!!!! I did and Josh was awesome.

Stillen's customer service is #1 (well, I have not dealt with Berk so perhaps I am not qualified to rate them). On the other hand, I spoke to Josh at Stillen in the afternoon, and the anti-fouler came the following day. Is this service or what!!!!!!!!!!

Both are great products, only thing I would think about is what exhaust you are getting after as the brand of hfc could determine the sound of the aftermarket exhaust.

I personally went with Berks because of the sheer amount of experience they have with designing and selling HFCs for VQ37HR engines. They initially adjusted the anti-fouler bungs until they hit the lowest rate of CELs which shows in the fact that it is very rare someone would get a CEL from a Berks HFC.

I got the ERZ HFC's as I can't imagine these two being that much better and I needed to save some $! Very happy and no fitment or CEL issues whatsoever. Any HFC will be fine.

I ‘would have gone with Stillen just for continuity sake, but I felt that anti-fouler should be part of the package without asking!
I also notice that the Stillen doesn’t have the support bracket for the brace that connects the right and left HFC together, that’s why I’m going with Berk’s on this one all else is pretty much even IMO!

Support bracket and proven fitment is why I went berk. Although, I find the FI resonated cat pipes intriguing...
