RCM headers alternative
Just wondered what everyone else uses , I've had two sets of RCM unequal length headers on my current and past car and both have cracked at the collector ,
So what else is out there that is tried and tested with good quality to boot ???

Most of the manifolds use the same material and same design, tomei, rcm, gt spec etc are all the same thing.

The killer b ones are 321 stainless which is a titanium alloy. They are super expensive. But come with a life time warranty even if heatwrapped.
I had the exact same issue, 2 sets of gt specs and a set of rcm all cracked. Would have been cheaper to buy one set of killer b headers to begin with....

Not really, been 304 stainless a turbo car exceeds to heat limits of this particular grade and causes it to go brittle.
