Hey guys, Im new to the forum, I have an 03 5AT G35 Sedan, with a 5/16" plenum spacer borla exhaust and injen CAI. Im wondering where I should go for HFCs, Berk or Fast Intentions? I can get Berk HFCs for about 440 or Fast Intentions for about 510, which would be a better buy? Does anyone have either of these Cats that can review it?

Thanks!

 

I don't have either. But I am buying a set of Berks next month! They sound amazing! Just my $.02.

Not being a smart ***, but why post this in the coupe section?

 

go Kinetix

 

I posted it in the coupe section because there are way more people on this forum with coupes, and they are more commonly modded, and its the same part for sedans and coupes, I thought I'd get a better response haha.

Do you have any sound clips of the berks?

 

That's very true. You'll get plenty of input here.

Here's a coupe with a Borla exhaust and FI HFC (Fast forward to 2 min):

Berk on OEM exhaust:

 

Motordyne ART pipes sound amazing

 

cant really go wrong with any of the HFC mentioned above...

Kinetix is also good... stock exhaust with Kinetix HFC

 

Fast Intentions HFC with stock exhaust

 

Man all these exhaust notes are amazing. I've never considered Kinetix. How are they on pricing??

 

The Motordyne ART pipes wont pass emission testing though...need it to be street legal where I live. Too bad though, Ive seen them make 18whp! I am liking the way all these sound, are they all pretty close on gains?

 

no HFC's are street legal according to fed law unless they replace OEM cats that have failed, meet emissions testing requirements and are replaced by a certified emissions repair shop. If your state does mechanical inspections and sees the aftermarket cats thay can demand to see the certification and give you xx number of days to remedy. If your state only does emissions testing then you may pass so long as you have no fail codes logged.

In my state (NJ) they recently eliminated the mechanical inspection and so we should have less need to swap cats every two years.

...of course some local shops that do emissions inspections never look at anything other than what will generate quick additional business likes brakes and tires...

 

Hehehe thats my video ^^

Also might want to check this one too!

 

Nice car bro. What are you lowered on??

And DAMN that sounds like !! Are those the FI cats on OEM exhaust??

I'm going with Berks after I have my smog check in January, I not totally convinced they'll pass our CA. smog sniffer test....
