Evolution Racewerks Sports Series High-Flow Catted Downpipes — S58 (G80 M3 / G82 M4 / G87 M2)

$2,335.00

Evolution Racewerks Sports Series high-flow catted downpipes for the twin-turbo S58 — G80 M3, G82 M4, and G87 M2. These replace the restrictive factory primary cats with high-flow 200-cell metallic catalysts — most of the flow of a catless pipe while keeping a catalyst in the system.

Catted vs catless

The 200-cell metallic cats clear emissions monitoring on the stock calibration (no check-engine light) and keep the car street-civil, where the catless Competition downpipes are race-only and trigger a CEL until the tune clears it. For most street-driven S58 builds the catted pipe is the daily-friendly choice.

What Evolution Racewerks builds in

  • Mandrel-bent 3" piping, 100% T304 stainless steel
  • High-flow 200-cell metallic catalytic converters
  • CNC-machined billet 304 stainless V-band turbo flange (factory 3.5" V-band); retains factory O2 location — bolt-on
  • 100% TIG-welded; made in the USA at Evolution Racewerks' California facility

Finishes

Brush, Polish, or our signature SwainTech White Lightning ceramic coating — choose above.

SwainTech White Lightning — our signature coating

When we coat a part, we use one coating: SwainTech White Lightning — a true ceramic thermal barrier applied about 0.015" thick (versus roughly 0.002" for paint-style "ceramic" finishes) and sprayed molten so it bonds to the metal instead of sitting on top. 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. Select it above.

Full S58 exhaust path

Pair with the Evolution Racewerks S58 mid-pipe and crossover for a complete exhaust. The catless Competition downpipe is the race alternative to this catted version.

What this is

A Part Recalibration is one focused revision built around the part you just bought. We take logs on your car as it runs now, on your current tune, then make a single full revision so this specific part delivers what it should. Hardware only does its job with a calibration shaped around it.

We bundle that tuning with the part right here, whatever brand the hardware is. If you want a fresh start across all your hardware, a Full Tune is the step up: a new base map, three revisions, and a written report.

This is a bootmod3 calibration. We tune through your own active BM3 license, so you'll need bootmod3 active on your car to load it.

Ships freight from Boca Raton, FL — additional fees may apply at checkout.

Step up to a Full Tune?

You've added a Part Recalibration to more than one part. At that point a complete tune does more for you: a Full Tune lays down a fresh base map and three revisions so all of your new hardware is dialed in together, with a written report at the end. We can roll your recalibrations into one Full Tune for $395 — below our standalone Full Tune, which starts at $495 for a four-cylinder and $595 for a six.

The Full Tune is a bootmod3 calibration — it loads through your active BM3 license, the same one you confirmed for the recalibration.

WHY WE SHIP EVOLUTION RACEWERKS
Cooling is the first thing to run out on a boosted BMW, and Evolution Racewerks builds the charge coolers and intercoolers that buy back the headroom. The bar-and-plate cores carry more thermal mass than the factory units, which is what keeps intake temps from climbing into timing-pull territory on a back-to-back pull. Their charge pipes also delete the factory plastic coupler that is a known weak point under boost. When a Stage 1 or Stage 2 car is heat-soaking on the second hard pull, a competition cooler from Evolution Racewerks is usually the fix that holds the tune's numbers session after session.
