Cracked Fabspeed Exhaust Header

I have had my Fabspeed exhaust for about 4 years and have been very pleased with it.

However about a week ago after a particularly hard track session, I came off the track with a strange exhaust sound and found this crack where the collector comes into the combined tube section.

I am planning to have it TIG welded for a repair, but I am a bit concerned as I have had race car headers repaired from overheating in the past, and they never held for long. It seems that once the metal temperature gets too hot, the metallurgy is compromised.

Anyone else have a similar experience and repair success?

Thanks for any info.

I found some cracks in my Fabspeed headers where the tubes connected to the plate at the heads. Repaired 2 years ago and still holding.

Way too many horsepower on that 90degree bent, my friend !

Seriously, that actually look like corrosion, from the pic you posted anyway. It would be kinda weird after <4 years however.

Call Fabspeed
Jerk that is constantly criticzing new forum members and overly advertising my rebuilt engine for sale for a highly inflating price along with other miscellaneous parts accumulated over my 20 years of ownership.

I've seen one other person reporting exhaust damage after going to wevo SS transmission mounts but of course I can't remember where, and it didn't make sense to me since the exhaust moves with the engine transmission pair and vibrates the same as it always did, just with more vibration sent to the chassis. If I can find that thread I will link.it here for possible ideas or debunking of that person's theory.
