Does today's Valvtronic Exhaust (e.g. by captristo, kreissieg or 9ff) have reliability issues?

since these exhausts have moving parts and wires/electronics/heat/vibrations are involved, how long are valvtronic exhausts expected to last before malfunctions occur?

 

there is a guy here named Scont who installed Techart exhausts with electronic valves. hopefully he will reply here, if not try Pm him hope this helps.

 

They are very popular in europe, I believe they even made the 996NA sport exhaust mechanism for porsche.

 

hi had my techart system for 3 months no issues at all. sounds great when you hit the switch and stock like when you want to cruise.
