Preorder will still be around $5k for the GT350. It is headers to tips and retains OEM valve control. Will also include CNC Engine brackets that are required for the headers to fit.

In case anyone is confused, OEM motor mounts stay. It’s just the metal brackets that change. Header design is double slip and isn’t 100% rigid so there shouldn’t be additional harmonics.

Concept 8-4-1 owner originally planned to force us into getting a GT500 / S550 dual tip valence to run the full system, but he’s now accommodating so there will be GT350 specific tips lol.

Hi flow or cats of some variation, or even resonators are a must. I just got back from the first couple days of Mustang Week at Myrtle Beach and it was downright entertaining to be reminded just how quickly and easily you can make a coyote/voodoo sound like complete ass if you’re not careful. I’m in hopes this system design is a game changer.

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.

Im a new to this particular setup. Does this increase HP over a traditional headers setup or does it just give you a unique exhaust harmony?

This is such a wild looking and hopefully sounding and performing setup. C'mon Sept 26th!!!

That's some full blown, gorgeous, NASCAR lookin sh&% right there! If this is a full system head to tail, no resonator/cat, and it balances (quality) sound & volume while addressing the rasp/trumpeting effect, that will be quite the accomplishment.

I know I'm not alone on this, but - I won't say that exhaust video's are completely useless, but they're close. Video's can give a little bit of a foundation on the sound at best. They do nothing to convey volume, especially an ear piercing long tube/no cat/open valve system at full send. But still curious to see what can be derrived from a video on this one.

You are absolutely right , but I have a feeling this is going to spot on .. if not I will attach some resonators somewhere to this dang thing lol . When I get mine Installed I’ll make some vids including DB readings and a frequency weighting graph so we can all see the changes in sound
