About damn time somebody offered HFC [rockon]

What are the specs on the HFC's? Ex. 100 or 200 CELL etc..

Do the sensor wires need to be extended?

Any pics from inside the engine bay to see how it fits?

What is the wait time on these?

Any issues triggering the Check Engine Light?

I'm confused. Why is a fouler needed if the two cats (the only two I understood had sensors) are still present?

Sorry for the confusion.

There are (4) catalytic converters on the 3.3TT Kia Stinger model.

(2) of those are located on the primary downpipe, and (2) are located on the midpipe section in between the downpipe and catback.

Since the primary and secondary cats are being removed, this would trigger a CEL on the vehicle. (Check Engine Light)

Even though the (2) primary cats are being replaced, they are being replaced with HFC (High Flow Cats) for performance.

Sometimes HFC will allow a too much exhaust gasses to pass through them, triggering a CEL.

So just to be sure, the fouler eliminates the need to worry about getting a CEL with these exhaust components installed.

Hope this helps clear up any confusion.

I've installed many HFCs on a few cars over the years and have never needed foulers. Does this part create CELs when not using a fouler?

And are there any dyno comparisons vs. stock?

Thank you!

When it comes to HFC, there are several different sizes out there, and some are smaller and others are larger. Due to the engine bay on this model of vehicle not having adequate clearance, the manufacturer couldn't use the same size as the orignial cats that were used from factory.

Since the HFC used in this kit are slightly smaller than the original OEM cats (which is what nets the higher HP numbers) there are some emission gasses that pass through still and that could possibly still trigger a CEL, so just to be sure, the manufacturer includes the foulers to prevent that from happening.

Dyno numbers are coming very soon!

Has anyone got these of their car? Any feedback? Anyone running with a JB4 or had any CEL or overboost issues? Thanks in advance.
