We've had our long tube headers in production for about a year now and are finding new and creative applications for them all the time.
These 997GT3 back box conversions are neat systems, we've done several now. I really like active exhausts and have developed our own active mufflers for several applications. The 997GT3 muffler sounds a bit better than the 991 version. The titanium version is crazy light which is always a plus. The system as a whole is not overly heavy and it looks more complicated than it is. The valve system is simple, they open when the engine is under load. Electronic controls can be added of course.
Tailpipes do require a valance mod. We make fiberglass units for this purpose.
