Review on Moroso 94055 Polished Stainless Muffler by Mardrequs Dorsey

I just got a noisy exhaust on a 3.8 Camaro hoping it would soften the tone and maybe reduce the rumble. The inner part of the tube has a spiral outer part. core and a straight inner core about 2-2.5 inches in diameter. Worried this might reduce the flow of my 3" exhaust. That part continues today so I'll be back with an update - UPDATE: The product helps a bit with the drone cruising and now there's no rasping. The only negative aspect is a noticeable reduction in performance. and acceleration.
