High-Flow Catalytic Converters

[GaryGolz]

Coulda just bypassed fabspeed and got em straight from HJS catalysts. Unless you just wanted a bolt-on affair.

Bolt-on and go! =)

Bolt-on and go! =)

Yes Sir. When the time comes I'm gonna bite the bullet and pull the trigger (wow, 2 puns, I'm impressed) and gonna go with a couple HJS converters.

Can we do a group buy on these ? is it a possibility

How do these compare to Kooks Green or B-Line high flow?

 

[tec548]

The B-Line are 300 cell count and these are 200's. These should flow better, but how much difference that would make is the question. I don't know the cell count on the Kooks.

 

[GaryGolz]

I'm not sure the exact catalyst B-Line or Kooks uses nor the power or size they support. I'm assuming it's a Gesi cat, which doesn't use the same wash-coating HJS German Cats do, but I could be wrong! Maybe someone on here knows.

A good factor to consider too when they're looking to change out to High-Flow cats is the end-cap. It SQUEEZES the exhaust gases entering and exiting where it's still very limiting to exhaust gas flow. You can see below how restrictive the end-caps the OEM have compared to the Fabspeed high-flow cats.

Essentially getting straight pipe flow, very similar sound, but no fear of CEL/Tune.

Definitely got my eye on this. Just need too see a couple other folks with similar results and no cel.

Just placed an order this morning with DJ with Fab speed ,can’t wait for me to get my hands on this and run some tests
Thanks Gary for the Help

 

[GaryGolz]

Glad to hear it Shawn! looking forward to getting your feedback!

Any fuel smell from these? Def interested, and am curious to see what others think of them once they get em bolted up.


Sounds amazing in the vid though

No fuel smell at all, the catalysts eliminate any odor.

There should be a handful getting into people's hands soon, that way we have more real-world tests and customer feedback.

Meant to add this, so you can hear the difference: GT500 with Borla Atak and High-Flow Cat sfor GT350

It sounds like the high flow cats sound more raspier and not deep. Would that be fair to say or it’s jus the video ?

It's really tough to accentuate the genuine sound and tone with video unless you have some REAL high-end recording equipment. I'd say it adds much more rasp and volume, since the engine rev's so high, you do get more high-pitched audio being a flat-plane crank.
