Yessir! After comparing to a few other exhaust company's results I am VERY impressed! For example, the F.I. exhaust gained 20.38whp over their baseline with the stock cats. Then they added their HFCs to the mix with the cat back exhaust and the HFCs only made an additional 3.54whp. Mainly because the cat-back already had freed up most of the bottleneck in the exhaust system. On the flip side, we tested the Berk HFC's with the stock cat-back and made 19whp, then made an ADDITIONAL 13whp with the cat-back exhaust. So if you take into consideration all of that then I think the Berk did very well compared to the competition!

Well when you put it like that, I guess Berk did alright.

I am sure we will find out exactly how they do in comparison as soon as the F.I. exhausts start finding their way onto Zs which already have the Berk HFCs.

Or, conversely, when someone puts a Berk CBE onto a car with stock cats and does a before/after dyno.
