This page collects TITANVEIN midpipes in SS304, Ti Gr2 and Ti Gr5, for the BMW B58 3 / 4 Series, the G80 M3 / M4 G82 / M2 G87 and the F80 M3 / M4 F82 S55. Looking for the part ahead of this one? Downpipes are listed separately in our downpipes collection.
Two designs are offered. A single midpipe is the simpler route; an equal-length midpipe merges the two banks with matched runner lengths, which changes the tone. G80 parts are available in 3.5 in, F80 parts in 89 mm.
What to check before ordering
- Confirm the chassis code — G80, F80 and B58 midpipes are separate parts.
- Match the inlet to your downpipe outlet: 3.5 in and 89 mm are not interchangeable.
- Decide between single and equal-length before ordering; they are different designs, not options on one part.
FAQ
What does an equal-length midpipe change?
It merges the two banks with matched runner lengths, which alters the tone compared with a single midpipe.
Will a midpipe alone need a tune?
No — a midpipe on its own does not normally require ECU work.
Where does a midpipe sit in the system?
Between the downpipe and the rear section. For how a crossover pipe differs from a straight midpipe, see X-pipe vs H-pipe vs Z-pipe.
Start here
Midpipes sit between the downpipe and the rear section. Choose single or equal-length first, then the bore that matches your downpipe outlet.
