Parts & Accessories Spare parts MagnaFlow Sport Catalytic Converter for SRT From Summit Racing, one of the largest and oldest performance parts websites in America. When it arrived, it was only one side, right, not both sides, and I couldn't install it (new in box). - -(You must order the second side, left) *Catalyst* MagnaFlow 52478 (High-Flow Direct-Fit) • Designed to be a direct replacement for the factory part (same dimensions and bolt-on installation). • Contains lower cell density → meaning easier gas flow. • The result: • Reduced backpressure. • Noticeable increase in flow, especially at high speeds. • Gives a deeper, sportier sound without being as annoying as a straight pipe. • Built from 409 stainless steel. • Does not disable the O2 sensor → the computer reads normally. � *Performance Comparison (Realistic)* • SRT engineers design the factory system to balance regulations + quietness + reliability. • A sport catalyst like MagnaFlow provides: ◦ Approximately +8 to +12 horsepower (with cat-back and headers, it might reach +20). ◦ Better sound and smoother airflow. ◦ Faster throttle response. •
