first off i tried to search nothing came up. just wondering if anyone used these and what the quality is, if their resonated or not and if there are any fitment issues.. thanks!

 

iv never heard of them... the best HFC are Fast Intentions and Crawfords but they are not cheap

 

I've never heard of resonated Hi-Flow Cats Test pipes, yes.
I agree on the Crawford recommendation, and can endorse them.

several people @ my350z have them with no reports of any problems, Mine are getting installed next week.


Also only test pipes come with or without resonators not HFCs

 

Quite a few people have had their HFCs and test pipes on the 350z board.
Their designs are almost identical to that of FI

 

I wouldn't take my chances with other HFC when Fast Intentions & Crawfords are proven & reputable products.

What's up with the rabbits????

You guys watch too much Andy Milonakis.

 

All they're just pipes and HFCs. It's really not rocket science. I've seen the Berks and they're quality looks far better than Fast Intentions or Cawfords. The mounting point of the HFC to the tranny brace is extremely beefy and the welds are the best I've seen. If I were to get a set right now, the Berks would be it. I've also seen a couple 3rd party dynos and there are some mild gains. With that said, I'm holding out for another vendor who will be releasing some HFCs in the near future.

 

will my exhaust tone become noticibly louder with HFC's? i'm looking to keep my stock exhaust sound but possibly make it louder and deeper. performance isn't important for me. would good HFC's do the trick?

 

yes...

go with fast intentions or crawford

 

I would back you up on this... The wall thickness of the tubing and casing for the catalytic converter substrate is very thinck, not to mention the very professionally done welds on the Berk HFCs.

There are more and more people getting the Berk's HFCs/ Test pipes on the 350z forum with 0 cracking/ fitment problem thus far.

 

Here are some small pics of mine going on this week





should compliment these very well

 

Have you compared the Berks with the Fast Intentions & Crawfords in person? I would find it hard to analyze a product's quality via computer images. Sure its not rocket science. But there are a number of products that do not function as they are suppose to. (IE. Borla headers vs any other headers).

I'm not saying that these Berk HFC do not work. All im stating is that I would not like to be some sort of "beta" tester for HFC that have not had many opportunities on VQ's thus far. Once they have been on many VQ's, and more data supports the fact that they do what they are suppose to do, I'll change my mindset. I personally would not get a product that hasn't had many chances on VQ's; therefore, not a 'proven' product.

I'm hopeful that these cats do the job like any other reputable HFC's out there. I hope people don't see my post as bashing or anything in that form... I'm just not the type of person that tries out newly released products that cost a good amount of $$$ (although they sure are cheaper than the other HFC out there).

The Berk CATS and pipes look to be welded on the outside, not the inside of the pipe and then strenghtened..like FI and Crawford.
