I can't imagine this on GT350...

Cats/Resonators won’t be offered the first round, but they’re open to it depending on how things work out.

With this manifold design it might take the pulse crash away anyways.

Tell the owner to offer a catted version! 1. For the smell and 2. I have to get emissions. If they went through all this R&D cost they are cutting off a large portion of the market without offering cats

Uugghhh...while I completely agree with you, if you throw in a quality cat like a HJS or similar...I think "ouch" is the word I'm looking for $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$.

Wonder what the primary length is? they look on the shorter side, so probably wont have the same gains in the midrange.

love the fact that they're equal length. those will be the first offering I've seen for Coyote/Voodoo that true equal length.

There isnt a ton of gain with headers normally anyway, right? I'm purely thinking about this for sound - any power increase would just be the cherry on top.

Or just buy and put a set of high Flow cats on it

Will be very interested to see if this is worth the sound on the CPC Predator Combo vs. the FPC in the 350. The DH video sounds really harsh down below about 4k rpm; almost like a res-delete x-pipe but it smoothed out in a beautiful note farther up the rev range. Hoping that is just the just the recording.

Interesting sound from their story highlight on the 350 taking a pull. This will be a system most likely have to hear in person. Now the question for me is a different sound but is it better than ARH to Corsa X to factory mufflers

Equal length headers should have come on these cars from the factory. Jamal Hameedi's 350R had them.

Agreed, my personal favorite setup on the GT350 is the full ARH system (w/ cats & resonators) that Obsessed Garage put out a few years back on YouTube. Need to hear more of the Concepts 8-4-1 still.

I do really like the sound that these headers are putting out on the S650 though.

The 26th is right around the corner ..MOOOHAHAHAHAHAH

I might be in the minority but these cars need resonators with no cats. That just sounds like noise to me.

I'd love to hear these monkeys without a reverberance from the surrounding area, decel is on the messy side but it was a very aggressive decel no denying that, and this vid is most likely on a camera phone and the audio blows . Not for nothing I will post good sound quality clips of mine vs Stock R setup showing DB vs Hz from a pre determined distance . Absolute worse case anyone can add a set of Resonators to kit if the choose..not sure about space constraints through. MMM MMMM the thought of this sound being force fed by 10psi will sound ANGRY AF!
