The factory part is squeezed into an oval for clearance and uses heavy cast sections, which adds turbulence and weight.\u003c\/p\u003e\n\u003ch3\u003eWhat it is\u003c\/h3\u003e\n\u003cp\u003eMandrel-bent 3\" piping kept full-round for a smoother path, 100% T304 stainless, CNC-machined billet 304 stainless flanges, 100% TIG-welded.

It cuts radiant heat off the exhaust by roughly 35–55%, dropping underhood and intake temperatures, and keeps heat inside the pipe where it sustains exhaust velocity and scavenging. And it's white — a deliberate signature in a market that otherwise all looks the same in black.

It carries no catalyst and is sold as part of a competition exhaust system; pair it with the Evolution Racewerks S58 downpipes and mid-pipe for the full run.\u003c\/p\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003eTwin-turbo S58 — G80 M3, G82 M4, G87 M2 (2021+ M3\/M4, 2023+ M2).
