Slightly different note, I like the long boi more almost. How's the difference in dB?

When will the hp figures be released for all 3 systems ?
Is there an advantage to the low mount system, or is it more for a different look ?

This is what I'm looking for but before I buy I have to see the full header system, collectors, and retention system.
Titanium ftw.
Id be surprised if this unit has what I'm looking for in a header. 🤷🏼‍♂️😉

And what is it that you're looking for in a header ?

I've studied header design for automobiles and top drag race teams in their header designs.
I've also dabbled in laminar flow theory so know a good flowing design especially coming out of the exhaust ports, collector designs, and and how exhaust extraction works via exhaust pulses timed via tube length etc.

I've seen a ZX25R header to my liking and had planned on purchasing because they were the only company that knows how hot gasses need expansion to fully deliver flow but because the 4RR has more displacement probably would not work.

All the top manufacturers show little of their header design although I'm sure they've been designed as best as could be allowed according to their budget for r&d.

I like this Graves short titanium sound and exactly what I'm looking for. Once dunno numbers are given with full tune I'll then make some decisions.
Until we get bikes in our hands it's no use to buy blindly when other tuners will finally have the chance to do some work and send out product too.

In spite of what I'm looking for we can't always get what we want so compromise is the name of the game and being happy with what's available suits me too. 👍

Would I be able to buy the cat back only of the low mount and buy the header later?

This is a full system with no cat converter.

Hey @Gravesport, any reply to the 2nd question, at least ? :)

The power curve is similar however with the works 2 (high exit) has a lower DB rating. There is also weight and aerodynamics to consider.

I know some decibel readings for 2 options were posted here somewhere, but do you have dB readings for all 3 options (cat back slipon, low mount, and high exit) ?

Thanks for the response Chuck. 👍

I do look forward to full specifications of weight and hp whenever you are able. :)

I'm on the list for a full system high mount but now I'm totally torn! The tail looks so nice without any clutter of a hanger or muffler.

Wish there was a way to have a modular option to switch from low to high with the same header.

Graves already said the slip on would work with the full header making it possible to switch. I don't think they've come out to clarify if the low mount would work in the same fashion.
I thought I read that the low mount couldn't be a slip on because of mid pipe shape

This is what I would love to confirm.

It is possible to purchase both and swap from low mount to the works 2 by purchasing the tail pipe / silencer / silencer strap and hanger mount

Thanks Chuck! I'd be going from high to low, so I'll ask if buying the muffler and pipe for the low too is an option once my system is ready.

I don't want to be greedy, I'll be happy with my full system and don't want to buy two setups when there are shortages to demand.
Any word on power output low vs high full system?

Nothing to post about at the moment. There are some folks out there who have our full systems and posting dyno runs along with their mapping.
