The Riot is where aggressive design and 2 into 1 performance collide in the ultimate upgrade system with attitude. The Riot will turn heads with its one of a kind custom look and rumbling, competition style sound quality. MagnaFlow’s signature Hi-Flow, louver core puts the power to ground with increased performance over stock. The powerful 1 3/4" to 2" to 2 1/4" stepped, stainless steel head pipes come equipped with a durable non-bluing Magna-Black coating and 12mm and 18mm O2 sensor ports. The bold 2 1/2" heat shields and laser cut junction cover add major style to this dynamic system. The innovative 4 1/2" tapered end cap with precision channeled profile and competition body style defines the bold look of the Riot. The Riot is the ideal choice for tuned engines and is available in show chrome with chrome end cap or deep black with gloss black end cap. Made in the USA by MagnaFlow.
