GESI Cats that will last on the track
 

Does anyone know of or have any GESI cats that have or will hold up on the race track?

Kooks says they have high output GESI versions that are better than their standard GESI green cats but they would not say if they would hold up to track use. The green cats I had melted after 2 twenty minute sessions.

G sport by GESI has some that are rated at 1200 hp per cat but again I don’t know if they would hold up on track. I’m going to call them and find out more info.

In my experience most high flow cats are a waste of money and break down quickly unless on a relatively stock car with no track driving.

Seems to be the case!

I'm waiting on a call back from GESI re their higher hp (1000hp per bank) cats, they are also larger and have a diameter of 5 inches (not sure if that fits) or even how to connect them since they are cores only

They never called me back, I just cut out the cats completely, smells like gas now but not a big deal if you’re not sitting in city traffic
