That is a wonderful thing.... Those will be on my car by spring!

thinking about getting these...since they're cheaper than FI's...should compliment my FI exhaust quite nicely

when released for g37?

They are already released in Berk's web site for $474.99

Can you use this wit stock exhaust?

Yea i believe so... Why not get FI's test pipes? I hear they have something in the works to take care of that check engine light :)

since FI's exhaust bolts right up to stock cats, that means berk cats should work with FI's exhaust, right? they're direct bolt-on replacements

Yea they should bolt right up.

wonder why berk hfc is so much cheaper than FI's..i got a quote for $475 shipped on the berk HFC...compared to FI's $599

Must be a different material.. I went to FIs shop and those guys are top notch... There product probably handles heat better therefor producing more HP

FI's HFC produces more hp than berk's?

I dont think they have posted dynos....

Terrible... were you guessin on the better materials part or do you know that for sure?

It's called effciency. We have more buying power and greater resources than most independent fab shops in the industry.

Who told you that? We use 304 stainless flanges, 99.99% pure electronic grade copper gaskets, A2 stainless bolts, the same Magnaflow metallic substrate cats.

And how about the most robust support gussets in the industry? Compared to.....

Handle heat better? What are you talking about?

Robbie Unser Jr's drift car uses what HFC's (yes, HFC's on a Pro Drift car!) and what custom center exit exhaust?
