listen right around 13 seconds, thats what a Stillen CBE sounds like when you really get on it, music to my ears. Sounds like a damn F1 car.

One question now that you guys are talking about Berk and Stillen...

If power was the only criteria to evaluate and both setups considered using Berk HFC's, which cat-back with produce more power? Stillen CBE or Berk CBE..??

So my question really is which setup would produce more power, Berk CBE/Berk HFC or Stillen CBE/Berk HFC...??

The thing is both sound really great to me with the Berk being more stock looking but that's about it...

Appreciate the input...

I don't recall seeing any Berk CBE dyno results yet...

Thanks Red370, that does sound really nice. I cant wait to look at the tests on the 2 to see power differences.

So far, independent dyno wise, the Stillen and FI have made the most power, averaging between 15-20whp per, havent seen any from the Berk setup yet.

Yesterday my car with Berk/stock cats went on a dyno (Dyno Dynamics) along with shawnal's (Alan) Z. Alan's car has the FI with large CF cans and also long-tube Injen intakes. He made 5HP more than I did, both pulls were within 1 hour's time, no temp difference.

Alan - 6MT - FI/Injen LT intake/stock cats 289hp
Steve - 6MT - Berk/stock intake/stock cats 283.8hp

I'll post my graph shortly.

So in a nut shell its safe to say the Stillen, Berk, F.I cat backs will all give 15whp increase.

But doesnt the Stillen run a Y-pipe? The dyno's and website claims a 18whp increase. Is that right? Where would the design of the stillen exhaust make up the numbers due to the setback of having a Y - pipe? I was under the impression the best gains come from a X-pipe, Please correct me if I'm wrong....

Nice collaboration on this one!

I can't show modeling equations or anything, but if the Y-pipe is designed well and has a large enough diameter where the Y merges, it shouldn't be restrictive.

I'm pretty sure there was a post with dyno results with berk awhile back before the 2 group buys. Not sure where they are to dig it up though.. let me look

DDMotorsports: Berk Technology Cat-Back Exhaust

Here is the dyno results. Baseline is with berk hfc and then catback is added on the next dyno.

baseline(with hfc)
1:280.80hp 244.28tq
2:284.15hp 243.22tq
3:281.29hp 248.50tq

cbe with hfc
296.90hp 250.91tq

EVL370 · 03-28-2010, 10:30 PM

Any links to the Stillen exhaust/berk hfc dyno results?

doesn't Semtex have a freak of a car though? Took to mods really strong? May sway things a lot without knowing compared to the norm.

Nothing i've read has shown the car to be a freak, his dyno results are right on par with mine with similar mods. His dyno charts are legit with results that can be expected with each mod.
