If Shiv designed it. It will not crack. I have bin sold on Vishnu stuff from seeing his upipe for the WRX. It takes a racing background to make a part that had that much quility and design in a simple pipe.

I'm saving my pennys as we speak. I want stage II. And I want it bad.

Are you willing to share you thoughts on what are the downsides of cast manifolds?

 

I will cast manifolds are heavy as ****. Cast manifolds retain heat (and radiate it)and increase underhood temps as well as affect the cooling systems both oil and colant temps. Weight is way above the centerline too
