Making my AMG GTS sound INSANE!
Upon replacing the factory's restrictive 800-cell catalytic converters with Fi EXHAUST's high-flow Sport 200-cell downpipes, the AMG GTS immediately exhibits a pronounced rumble at idle. When the valves are open, the sound volume is dramatically enhanced, accompanied by sharp pops and delightful burbles in the exhaust. These acoustic enhancements are particularly noticeable during downshifts.
