HKS Hi-Power too loud with HFC

roy'sz · 05-12-2013, 04:05 PM

I bought mine right from arks website.
Nissan 370Z and Infiniti G37 Coupe/Sedan | R-Spec Hi-Flow Cats 2009-ON | 3.7L

I paid 680 in December last year. installed was 720. You will have the normal hiss but it isn't that bad. I am extremely happy with my setup and recommend it to anyone!!!

Also where did you get your ARK resonated HFC's from? I could not find them in the marketplace here on the forum or on their own website.

I understand. And I appreciate roy'sz and other people has jumped on to this and tried to help. So is myself. I am here just trying to give my best advises to help op get the right products that will put smiles on his face. That's all.

Let me know if you want to roll to F4's on Wednesdays I believe at Applebee's in Independence. I know its forced 4's but lots of people with everything show up and I've been going for 3 years and know almost everyone. Also I might take the Berks if you need to quite it down with something else.

Okay, so I finally installed HKS Hi Power today... To my surprise, the Hi Power + stock cats is very quiet just like the stock Nismo exhaust. But I still like the tone of it. I've heard test pipe + hi power combo at local meets. That is day and night different!

Now, I want to get the HFC for myself too. My question to OP... After you install the berk, do you feel power lose at low/mid end? That's what happened when I had FI hfc and FI cbe and this is my biggist concern to get the HFCs.

Thats why I got th motordyne manfold and tune. I have a lot more midrange power than when I didn't have the manfold.

That's nice! I heard the md manfold gives you a lot low/mid power. Unfortunately, I can't tune my car in Mass. It will fail the inspection.

New law this year.

I still have my stock map included with the uprev.

Yeah I am definitely down for that. I will pm you when I am free. How often do you go?

I am going to get some resonated HFC's for sure so when I get them I will let you know so you can have first dibs on my Berk's to keep it local!
