Exhaust work on the S58 starts at the turbo outlet: first decide whether you touch the downpipe, then the midpipe and the rear section. This page collects every TITANVEIN part for the G80 M3, G82 M4 and G87 M2 — SS304 and titanium, downpipes with and without a heat shield, equal-length and Z-pipe midpipes, and standard or valved rear sections.

Downpipes come in 3.5 in and 3 in plus a 95 mm version, with a 200-cell catted option for owners who need to keep a catalyst. Equal-length midpipes are offered in SS304 and Ti Gr5; the Z-pipe midpipe adjusts tone and backpressure. Rear sections run from SS304 through to carbon-fibre tips.

What to check before ordering

  • Confirm the chassis code and model year first — downpipe flange fitment differs between some G80 M3 and G82 M4 build years. Check the Fits field on the product page.
  • Plan for a tune: a catless downpipe usually triggers a check-engine light and normally needs ECU work. Confirm the approach with your tuner.
  • Catless downpipes are not road-legal in many regions. Check local emissions rules before ordering.

FAQ

Are G80 and G82 exhausts interchangeable?

Most of the same platform shares fitment, but rear hanger and tip positions differ. Use the Fits field on the product page.

Titanium or SS304?

Titanium is lighter with a sharper tone and costs more. SS304 is the more durable choice for daily use and easier to repair.
