Default ERZ HFC owners

Anyone out there that has bought the ERZ HFCs? Im wondering if you have had any cel light from it yet? And if you can tell if there are gains? And is there any rasp from it? I love their price, it seems that they are thinking that lower prices might mean higher sales. From what I can tell they are using metal cats and 304 steel so quality seems to be good. Thanks.

I bought them (think I was the first on this forum). Check out my other thread for a review and video.

Quality is excellent. T304 SS, 200 cell metallic core, and includes right angle anti-foulers. No CEL and I've had them for about 350 miles so far. They open up the sound of the Stillen CBE really nicely. There is a touch of rasp added only under WOT around the 4-5k RPM range. The VQ37 off-throttle hiss is also accentuated by these HFCs but I think this is a quality of any HFC on our cars. Overall, I'm very happy with the ERZ cats...I'd buy them again in a heartbeat.

could you feel any gains especially since you already had a CBE?

Hard to say with my winter tires still on the car. My inclination is 'yes'. With the winter tires, I'd get a VDC light on the highway if I dropped to 4th and floored the accelerator. With the HFCs installed, it happens in 5th now too. I'll have a better idea once I get the summer tires back on at the end of March.

I will be installing mine on Saturday. I will report back what my butt dyno says. I am also getting my car Dyno'ed the following Tuesday so I can see what I picked up from a CBE, Intake and the HFC's.

ZSteve - ERZ is also offering a discount (PM the ERZ sponser) to those who post a video with there HFC installed.

SpearFish25 has the Stillin CBE convered, I will have the Invidia Gemini covered...I do believe there is no video's for FI CBE. There might be an opportunity there for you.

No CEL's, no problems and they sound good with stock cat back exhaust.

For those who purchased the ERZ HFC did you recieve the angled Anti-Fouler (Show in the Picture Attached)? I did'nt recieve this extended Anti-Fouler but did not see it on the sponsered ERZ Sales Tread pic either (Link Below). Should it be included with the HFC Purchase?

I called to ask about the anti-foulers when I received them (that's my picture). They said they just started including the right-angle anti-foulers. You can probably call them and see if they'll ship you a pair. Who knows if they really make a difference or not...I suppose time will tell.

Doubt it. The rasp I can hear really comes from the cats themselves. I'm interested in the resonated version on the horizon, but I'd hate to lose some of the volume the HFCs added to my exhaust. I'm not sure I'd pay the price premium and take the volume loss of resonated cats given how nicely the non-resonated HFCs have turned out.

So did you already have the CBE on and then get the HFCs? If so how much louder did it make it? Thanks.
