Review on 🏎️ Enhance Performance with Thrush Thrush Turbo 17654 Exhaust Muffler by David Fisher

I didn't like that the 2.5" diameter tube was just inside to almost 1 5/8" The shrinking muffler, which restricts airflow and creates back pressure, negates all the usual benefits you would expect from a straight-through-bore dual exhaust system that keeps all components down to 2.5 inches. I will not use this silencer due to its restrictive design.
