Vibrant 7100 HFC for midpipe (secondary cat replacement)

BIMMERPOST / Classifieds
Asking Price:
Sold
Location:
✓ Will Ship
Item Interest
I have two Vibrant 7100 high flow cats for sale.
These cats replace restrictive factory secondary cats (cut and weld required).

I put these on my factory midpipe during thanksgiving week and used it for 300 miles.
Then I decided to buy ETS full exhaust during black friday sale.

Price: $150 shipped or $130 local pick up

PM me with any question.

Thank you,

Specification:
Inlet Diameter - 2.25"
Outlet Diameter - 2.25"
Outer Shell Size - 5.25" O.D.
100% Stainless Steel construction
Metal Monolith is much more resistant to the effects of vibration than traditional ceramic bricks.
Capable of withstanding higher operating temperatures.
300 cell per Sq. Inch catalyst flows at 578 CFM, up to 40% better than a typical ceramic core converter.
Suitable for use on engines up to 5.0L
50,000 Mile Limited Warranty

Dont have exact cell count but it is high.
I wasnt able to see anything when looking through stock mid cat.

Reason why I initially installed these hfc together with catless downpipe is because giac told me that i would notice about 20-30 hp difference with their tune if i have stock secondary cats vs not having them at all or replace with hfc.

I think the cell density on the stock ones are around 600 cpsi. For comparison, high-flow cats are 100 - 200 cpsi.

This does not change exhaust tone. It just makes exhaust little bit louder.
You will notice most difference if you mate this with catless downpipe.
