Berk catalysators on track any issues with the heat?
 

I could shoot some berk cats for extra hp, but im concerned about the heat of the berk cats, because they have no heatshield.

Has anyone experienced these cats on track so far?

Thanks!

You'll be fine.

Mine broke. Elements came loose and rattle around. Only did two track events. No more Berks for me. I went to long tube headers.

I didn't about 18 track days on mine, had no issues. They still looked good when I pulled them off.

The main issue of concern is the proximity to the clutch line, I suggest adding extra insulation to the clutch line to help protect it. You can also use some header wrap tape on the Berk's to reduce heat radiation at that point.

I've had my high flow cats (ERZ Performance, but no heat shields) on the car for 20k miles and I've done about 15 track days and innumerable autocrosses with them in some very hot weather. Aside from putting RBF600 in my clutch, nothing else has been done to shield any heat. No clutch issues ever.
