Jazz Manifold.

Anyone running one these manifolds? They claim better spool since the manifold has smaller runners. I'm curious if anyone has a real world review of this manifold and or dyno numbers? Just trying to get an idea of how much rpm is gained on spool up. Thank you.

I haven't noticed much discussion of them on this forum. However on social media (Instagram/FB) i've read a lot of happy/good reviews from people. Definitely nice to see someone come to the market with a new product, and these sound rowdy as well. Which I believe was the original intention of these, a low mount, sturdy T2 manifold that has a similar sound as the old fragile td06 greddy manifolds.
Check out recent videos of Julian Jacob's s13 that's running this manifold.

Yeah i like the sound of these. Don't think it's quite on par with TD06 manifold but it sounds more like an angry WRX due to the unequal lengths.
