_______

The GReddy SP name carries decades of street performance credibility, and the Supreme SP is the best version of that legacy yet. From the first flange to the new double-wall GReddy tip, the entire system is hand TIG-welded 304 stainless steel — the kind of build quality that earns a limited lifetime warranty.

New straight-through and directed straight-through chambered muffler designs let GReddy tune a more refined exhaust note while actually increasing flow and performance, rather than trading one for the other. Classic GReddy street styling carries through the whole system, with fitment and layout designed to match your Si's body lines rather than look bolted on as an afterthought.
