The end-muffler weight is about 6,5kg. I think we are lighter than Akra, because we use a titanium with 1,2mm thickness, think Akra will use 1,5mm.
The titanium we use is builded in Japan, Special made for the high temperature in exhaust using.
Titanium is a fine material, but it's tricky if the temperature grove over 250-300 degree celsius. Normal titanium (Grade 1or 2) can not be used and will brake down after a while. Akra takes also a high temperature Titanium.

Valve Control: We thought a lot about this Option and builded two sets of this. But the Sound wasn't as good than we thought. You Need a complete exhaust System to get the 1M louder than Serial. For that, we builded a loud end-muffler. 90% of our customers in Europe take this Option, because the Sound, only made by the end-muffler, is really good and you can save the Money for a complete System.
