HFC confusion....

Astrosfan · 06-29-2011, 11:05 AM

So, I have my HFCs waiting in my garage to be installed. After calling several performance exhaust shops, no one wants to install them. They say that the stock cats have the same guts as the HFC and there really isnt such a thing as HFC and that they will cause more problems than whats its worth. Also, that they are all made pretty much by the same cataltic manufactures and im just wasting my money. Is there any merit to this? Ive read tons about them from this site, i just want to know where they are coming from? I mean, if everyone is seeing results, then i'll take proof of gain over what some guy says, im just wantng to know where they are coming from on this?

Thanks, i just need some clarification!

No clue where they're coming from, but there is plenty of evidence of proven gains here on the forum.

Cores all the same made by Magnaflow, with different fabrication companies manufacturing the end result. All HFCs, assuming identical size and cell count in core, will net the same power.

My car put down 287.5 on the dyno, they jacked the car up, installed the CNT HFCs and then ran it on the dyno again and it put down 304.

Plus it sounds really mean now under throttle!

Go somewhere else, they clearly don't want your business.

and I don't blame them. They face a $25,000 EPA fine for installing them.

I'm surprised nobody else mentioned this. Unless emissions equipment is faulty or defective, it's illegal to mess with it.

The OP is in TX. As far as local emissions regulations go, even in the big cities with stricter rules, installing aftermarket HFCs (which are emissions functional, not just some empty shell) is perfectly fine.

As far as the feds go: the EPA regs are about improper catalytic convertors. You can install aftermarket converters and still be in compliance with the EPA. They just have to be correct for the car in question and be fully functional, and carry an EPA designation on them. I think it's safe to assume major manufacturers aren't churning out non-compliant HFCs, because even *selling* such an HFC is worth a $25K fine per unit to the mfg, if you go read the EPA docs. If in doubt, I guess you could ask the mfg?

Either way, HFCs are a common upgrade performed by lots of shops all over Houston, and you can get a state inspection with them just fine (and I don't mean with some under the table ******** - they'll pass anywhere in the state randomly).

Except the fine has nothing to do with actual emissions, and everything to do with removing functional equipment.

Kind of ironic comment coming from you, didn't you have a TT S2k?
