Unlock the full character of your Coyote V8 with this premium Remus quad-exit rear system. This straight-through, non-resonated catback delivers a deeper, louder, motorsport-inspired soundtrack while keeping the convenience of factory valve control. Hand crafted in Austria from high-grade stainless steel and finished in a bead-blasted sheen, it offers precision fitment, reduced restriction and a purposeful look with 102 mm quad tips.

We run this system on customer cars and the feedback has been outstanding. Sharper throttle response, addictive tone and top-tier build quality. If you want your S550 to sound the way a V8 should, this is the upgrade.
