I'm assuming this a pretty much straight-through design? If it equals other low backpressure exhausts and is several pounds lighter, you may have something. What grade of Ti is he using? You said he ran an aerospace company, so I'm guessing aero grade? That would be 6% aluminum, 4% vanadium; or 6% aluminum, 6% vanadium, and 2% tin - I think that's right. That stuff is rather expensive as I understand it. The people who flock to titanium are going to be the ultra high performance crowd looking to shave off a few pounds wherever possible. For this reason, he might be better off doing full cat-back systems, or just pipe sections.

I'll tell you what I might be interested in. If he made some mandrel-bent joints and inlet sections for welding together turbo manifolds, he could probably peak the interest of a few builders. Making sections would probably be better since he would be limiting applications significantly by making whole manifolds. He could sell the pipe sections to shops that make manifolds, and I guarantee you the shops would find a good way to market them. It would be nice to have a true alternative to cast iron manifolds (tubular aluminum does not work. I'm not sure if ExtrudeHone does titanium, though, since it's a bit harder than other materials they work with.

Ti exhausts seem to be most popular on high performance import motorcycles. That would be a good start. Only problem there might be all the new variable exhaust systems they're fitting on those. Hmmm... I don't really give answers, do I? I just come up with more questions... :smoker2:
