I think it's partially due to the lack of a cross-over or X-pipe. It could be affected my muffler baffle design ... or even installation. My last set of CC's sidepipes I ran were simply 3" ID inserts, which slipped into my straight 4" (lake style) sidepipes. I installed them backwards, with the louver "scoops" not scavenging exhaust into the outer chamber. That resulted in max flow with minimal sound reduction. I also had ZERO "flutter". Fast forward to the new set of CC's Cobra Packs. Same muffler design, but with fiberglass in the outer chamber. I installed these with the louvers scavenging exhaust, resulting in a little flow loss but better sound reduction. Now I have flutter.. Was it the different outer housing, the louvers installed in the scavenging manner (that's what I think) or ... the addition of the fiberglass packing..
The "flutter" quandary marches on...
