ERZ Performance High Flow Cats, Install and Review Thread

spearfish25 · 02-16-2010, 04:02 PM

Hmm, don't know what to say about the curvature of the triple bolt flange. I don't recall having quite as crude a junction between the inner tubing and the flanges as you have there. IIRC, mine looked like your pic with the two bolt flange directly facing the camera...you can see the inner pipe just inside the flange, but there weren't any gaps or beads of weld coming through.

I'm thinking the curved flange will be ok once everything is tightened up. If I have a leak I'm sure ERZ will take care of it.

It seems like the gap in the flange and tubing is pretty similar to the last pic in your original post.

It's a little hard to tell since that part of the picture isn't in focus though.

give me a call tomorrow I can switch that one for you, seem like the welder was lazy that day doing that one.

I'll send that one back to the factory and get it grind.

Well now...don't I wish I looked mine over more thoroughly. Fortunately they're performing really well. But who wants to have to do their own quality control?

What about the flange curvature all these guys have been noticing?

Yeah that doesn't seem very fair to you. I guess if you're happy with the end results it's not a big deal though?

Awesome! Thanks for taking care of it. I'll give you a call on Friday to work out the details.

I have curved flanges too on my ERZ HFC's. Not sure if this is an issue or not. Interested on what ERZ has to say about it.

I am hoping that the consistancy with the curves means that they intended to do this.

spearfish25 · 02-17-2010, 06:21 AM

Yeah, I wouldn't make too much of this until someone has personally spoken with ERZ or had an issue after install. They are very receptive to phone calls and will give you a good answer.

My install went very smoothly and I've had no issues with any leaks or problem. Given the consistency of the findings, I'd talk with ERZ before jumping to too many negative conclusions.

bluestyle55 · 02-17-2010, 09:10 AM

I agree! I will give them a call today.

Yeah please ask them about the tubing sticking out in the inlet. I don't think grinding away at it is really even an option since it doesn't look like there's much material there to work with.

199!!!!! for a resonated test pipe!!! Damn i just bought a set from GTM!!!

bluestyle55 · 02-18-2010, 08:01 AM

I took a look at mine last night (deep sigh...been waiting to get them installed. Finally going on this Saturday) and it looks like they were grinded down a bit to ensure a flush connection at the flange ( So quality control was done on mine

).

TBSS2008 · 02-18-2010, 09:57 AM

Quality looked good on mine as well. The guys at Import Performance Specialist who installed the HFC commented on how well they grinded the inside of the pipes. I drive a lot and have already put 750 miles on these HFC in two weeks. No CEL and no leaks!

On a side note I got the new NT05 Tires mounted right after the HFC. These tires grip like no other. Makes for some really fun driving. At high speeds and cornering the NT05’s really shine. I thought the Bridgestone Potenza were a bit twitchy at high speeds not very confidence inspiring.
