Stillen Exhaust with Berk HFCs

Endgame · 03-08-2009, 11:20 AM

Semtex... AWESOME clips.. Thanks for doing that work man!!! She sounds LOVELY!!!

Do you think as the exhaust ages it will get louder? Right now, it is just perfect!!! I think I may have been convinced to do the HFC thing....

I second that...great work. Looks and sounds awesome.

My MB Z is on order...so I have to check out all your pics and vids in the meantime. Keep 'em coming.

Semtex,
Great job on the sound clips, posts and install pointers. The combination sounds perfect. Do you have any plans to get a dyno done? It would be interesting to see a dyno before and after a tune with the combination (HFC + exhaust). I'm considering a similar setup but also includg a CAI, most likely the Stillen long tube.

Thanks

Wow! Great videos. That sounds amazing. Either that camera picks up the sound really well, or it is pretty loud, because on the drive by video, you can hear the car even when it's all the way down the road. Sounds great though.

Nice. VERY NICE. Thanks for the clips - very helpful.

Eventually. After the CAI and a tune. Possibly headers.

Nice work with the clips and whatnot. I'd love to see what your car puts down numbers wise.

tvfreakazoid · 03-08-2009, 08:51 PM

Not bad of a sound. But I would prefer it to be louder.

semtex · 03-08-2009, 09:00 PM

It IS louder, quite a lot louder, actually. Bear in mind that I'm using a digital camera to record these. The microphone isn't the greatest. Think of the difference in how cars sound when you watch a race on TV vs. how it sounds if you actually go to the track. Hard to do the real-life sound justice.

I apologize if this has already been posted, but are the HFC street legal and meet emissions?

They are 49 state compliant, with California being the odd man out (go figure). Shouldn't be a problem with emissions. Keep in mind that these are actual catalytic converters -- they're just higher flowing ones is all. It's not like they're test pipes with no substrate material to filter the emissions. You can also look at Berk's website if you want more info.

Sounds real good Semtex. I can't wait to install my BERK HFC's. I didn't have time this weekend. To much yard work to start on. It's just that time of year. But I did install Jim Wolf Popchargers since that only took about an hour. Those with HFC's and my Nismo exhaust. Should sound good and clean. Maybe next weekend.

Sound clips por favor?? I am REALLY interested in your setup... PLZ POST!!!!!!!!!!!!!!!!!!!!!

Although, this will pass emission, here in California, you'll fail visual inspection.

Semtex... your Z sounds amazing! Are you considering in dyno tuning it?
