CNT HFCs? Does anyone have them?

shika805 · 02-15-2013, 01:06 PM

Hey guys,

I'm in the market for another mod for the Z and was looking at some different HFCs. I've heard a lot of good reviews on the berk tech HFCs and stillens. I came across CNT RACING HFCs and it doesn't seem like it's very popular here. I've only seen a few people here running their exhaust but haven't really seen anyone with their HFCs.

Wanted to know if anyone has experience with their products? Any good reviews on sound, quality of product, fitment, power gains or any issues?

I've searched past threads but not much info on them. Any info is greatly appreciated. Thanks in advance.

I installed mine a few hundred miles ago. I don't have any issue with fitment. I installed mine with cbe, so I don't know what it sound like without it. Loving it so far with that price.

I have the their HFCs installed. They've been on for about 13,000 miles and no complaints so far. No CEL without any extenders for the o2 sensors. I would highly recommend getting the Z1 metal gaskets. The gasket that was with the package was leaking within 1000 miles.

Thanks for the input, I'm going to pair it with the ark grip exhaust. I wonder with a good tune what type of gains will I produce.

I saw on the website that there are new extenders for the o2 sensors now?

Have you guys gotten any warning lights coming on?

i have the CNT with ARK grip 2, sounds loud IMO. instead of buying o2 extenders, i stuffed in a tightly rolled ball of steel wool in there. 20k so far and no CEL after the steel wool.
