I´ve just got a new ASP FS 61 AR. Unfortunately, the muffler manifold angle is not large enough to get the muffler under der cowl. I do not know if ASP sells any different muffler manifolds. Could I use Saito exhaust accessories?

Even more, both (!) muffler nuts provided in the box are scrap metal. The screw thread has not been cut right-angled into the nut. Thus, these nuts would never do their job soundly. Do Saito muffler nuts fit onto ASP engines?

(...asked if I would buy another ASP FS 61 AR I would answere "no".)
