Those variants are a lot more expensive so the cost would be a little over double and they dont make direct ti weld on versions. Both my ti suppliers have cat options only in the high flow range. Also all my material is American Made.

Who’s your USA titanium CAT supplier? That’s great to know there are stateside options.

Sounds great!

I'd like to keep my supplier anonymous considering it was difficult to setup the business relation.

What's the mass of these without resonators/cats? Do you add mounting features for the exhaust center support? These look really nice, definitely tempting me with the price/proximity

Agree with this, would like to see the factory mounts added up front and center support brace. What rear section in video?

This version was chosen to not have any supports as it was the first prototype, expected to make changes etc. to it but ended up not needing to. Mass is currently unknow but CAD mass 8.35lbs, whole bottom end was 3D scanned so fitment wouldn't be an issue. Because of that adding the supports is no problem.

Once I remove the exhaust for smog i'll go ahead and get an official weight or if someone order in the meantime.

This is factory rear section, that video was the first test day with exhaust and there was a small leak due to fastener being loose. Please look at previous thread reply regarding the supports. But in short all customer systems will have supports.

This is going to be my next mod. Local shop quoted me almost double for a Akra gt4 style xpipe in titanium.

Have you come out with any pics with of current version with hangers and installed on car?

Will order soon.
