Berk HFC dyno results

Red370

also posted in the general section, figured I'd post it here under exhaust, particularly because people come to this thread to find out about results with exhaust mods..

Before Berk HFC's


After Berk HFC's


15whp gain, was unable to obtain TQ numbers due to the tech being a dumbass.

Thanks for posting this! besides the nice gains, how do you like the HFC's sound wise? I have them too (with stock exhaust) and can feel the performance gains but I can't stand the sound. Especially after hearing the Stillen CBE on another forum members Z...

He he he...let me know when you're sick of your cats and we can try them on my car to see just how it sounds.

Josh@STILLEN

HFCs provide some amazing gains.. "feel-able" gains.. those are good numbers. We've seen the same result.

JB1, I know Monday the STILLEN CBE's are going on sale, keep an eye out if that's a consideration, should be a good deal..

I LOOOOVE the way it sounds, almost afraid to get a full CBE because I dont want to change it. If I do get a CBE though, its gonna be either the Stillen or the FI, if I can get the Stillen setup cheaper, im gonna be going with that one.

As soon as I'm ready to rip them off, I'll let you know :-)

JB1

Can you do another sale towards the end of the year? I should have my x-mas bonus by then... Piggy bank is empty at the moment :-( (otherwise I would order the CBE on Monday and spearfish could have tried my HFC's )

spearfish25

Yeah, but once you hear them with the Stillen CBE, you might want them right back!

JB1

Check the private classifieds on this forum for a good deal on a Stillen CBE (sorry Josh).

The sound of the HFC's is to raspy (or dare I say, Ricy...) for me. I heard the Stillen exhaust with stock cats and that sounds sooo good, real nice deep sound, not raspy nor ricy... oh and this is heard from inside the car, I don't care how it sounds from the outside, I don't hear the outside when I'm driving

JB1

Hey, I said you could try them, not keep them


No, all joking aside, I think CBE + HFC combo is too loud for me (yeah, yeah, wuss...)

Josh@STILLEN

Hey.. if you can find classified deals and stuff is in good order, nothing wrong with that. Just be sure it's not welded or has some other permanent modifications to it.. each Z can be a little different, can cause some headaches trying to move welded exhausts around.

And I would imagine there would be something around the holiday season, not sure if it's as aggressive as what's happening on Monday, but we definitely try to do what we can to give the holiday shoppers a chance to spread things around.. such a tough time..

spearfish25

Of course I'm curious what this amazing deal might be on Monday. I got my Stillen CBE at a darn good price with a rebate to boot.
