This performance exhaust upgrade features a big-bore 3.5 inch U-bend that transitions to OEM-spec diameter for maximum flow with seamless system integration, making it a standout choice among high-quality downpipes. GEN 2 provisions support hybrid applications for expanded functionality.\u003c\/p\u003e\n\u003cp class=\"redstar-intro\"\u003eDeveloped using 3D scanning and reverse engineering, the long 3.5 inch section and flow-optimised transition to 3 inch target reduced backpressure for faster spool, sharper throttle response and tangible power and torque gains, while adding a richer, more engaging exhaust tone. GEN 2 adds extra sensor bungs and thermocouples on hybrid models, a capability not supported by the GEN 1 M256 Downpipe. Optional OEM-style heat shielding reduces radiant exhaust heat by up to 80 percent to help control under-bonnet temperatures.\u003c\/p\u003e\n\u003cp class=\"redstar-intro\"\u003eBuilt from 2.0 mm wall 304 stainless steel, each Redstar downpipe is 100 percent TIG welded and back purged, and finished with OEM-spec flanges and brackets for a true bolt-on fit. Choose Redstar for precision fitment, optimised flow and lasting durability in your Mercedes performance exhaust.\u003c\/p\u003e\n\n\u003ch2 class=\"redstar-section-title\"\u003eAvailable Options\u003c\/h2\u003e\n\u003cul class=\"redstar-options\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHJS HD 200cpsi Catalytic Converters:\u003c\/strong\u003e Engineered in Germany and trusted worldwide, the HJS 200cpsi ultra high-performance cats are rated for over 1000hp.
