Biggest difference between cheap and expensive hfc

puckshaw

Bingo. I've seen the difference for myself.

Who's got top "cheap price tag" build quality that someone has seen first hand

Jordo!

Could you elaborate...?

I can't speak for him, but I can honestly see it in the difference in quality of anything in the automotive aftermarket industry.

Compare an Amuse cat back to an Agency Power. (I hate to say it) but Agency Power stuff is made in China and Taiwan. There is a wholesale company overseas that sells all of the parts that AP brands and sells under their own name.

The Amuse stuff is by far some of the nicest, highest quality stuff I have ever seen and the AP is just a low cost, copy.

You can see it in the thickness of the pipes, welds, and quality of the hardware... it's very noticeable.

I'm not trying to call anyone out, but if you look close enough, you'll see it. You get what you pay for... remember that.

I have ERZ HFC's (china built) and JIC magic Y pipe (japan built) and I have to say the Y pipe looks a lot better built. For me its not a big deal because its something you cant see, and overtime looks all discolored from heat. As far as I know performance wise (cel count) its the same as the expensive ones. I did not have any issues installing or defects on mine. Hope this info helps

Sure, it might not apply for some things. China and Taiwan supply a large majority of the worlds auto manufactures with parts. In some cases, you can buy directly from the same company overseas that supply an OEM company.

Obviously that isn't feasible for all companies to do that because it requires such large resources to do so, but it is possible.

I want cats but I have a concern.

I've heard and seen first hand on my friends S/C 350 that OEM cats can crack on FI and NA cars. Sometimes the particles can be sucked back into the head and score the cylinder walls and rings. How many aftermarket catalytic converter core manufactueres are there? For the ones made here like Berk, Stillen, FI sure there are build quality differences, but how do you know you are not getting the same (for example) Magnaflow core with nicer welds and flanges?

I can't really say for sure, and I don't like to spread misinformation but my friend says he read about people on the 350 forums cracking Berks. I don't know if it's a few people and it's blown out of proportion compared to happy customers or what. Maybe it's the most popular so you hear about more failures?

How does a customer know what kind of heat these things are good for? I think with the well known engine heat the VQ has I'd probably want something designed for a turbo car. I guess we're probably not going to know until people have had these for a while and you just get what you think is the best at the time....

I think the only real way would be to get the companies information on where their cores are coming from. As a consumer and end user, you would have the right to know.

If you are getting a part made over seas which is being used in other brand parts (some who have or haven't had failures) it would be important to know.

If company X uses parts from manufacturer Y, and company Z also uses Y parts, then X and Z should have similar results as far as longevity. Take into account MSRP for both X and Z parts.. then you'll have something to compare.

Well... okay.

But what I mean is, so long as nothing cracks or leaks, and everything bolts up, it probably doesn't really matter if it was made in a sweat shop in China or lovingly welded by elves in Wonderland.

How it looks doesn't really matter...

My point though is how often does a guy look at the inlet side of the cat after install? I'm talking about the mesh media inside, not the welds. I'm willing to bet never. How do you know it's not cracked at some point down the road....? I'm not saying anyones stuff here is bad, it's just a concern. I want something designed to handle the heat of turbo charging, even if I never go that way.
