BMW G80 M3 Competition (S58 - 510 Hp - models with OPF) 2021 -> (with valve)

aka: Performance sport exhaust for BMW G80 M3 Competition OPF

Supersprint is proud to offer its complete range of Performance exhausts for the 2022 BMW M4 Convertible; for both the US and the Euro (OPF-equipped) versions.

Our multiple Downpipe-back offerings include a "Twin Pipe" system, and a unique, "J-pipe" (single pipe) system, each providing for distinctive, unique sound harmonics.

We also offer a California-only, exclusive version, which deletes the stock resonators, while keeping the secondary cats in place.

Come think of it, this specific system offers a nice, audible sound improvement, without affecting the emissions even by the slightest amount.

Each of our exhausts are designed to accept the std factory muffler, and the MPE muffler as well, with no modification required for the install.

All of these Supersprint systems are a bolt-on and go application, fitting just perfectly, with no interference to the cross brace, thanks to a proper routing and the narrow-radius mandrel bends of the pipes in this critical area.

No spacers for lowering the brace are needed either.

Speaking in terms of flow, they guarantee the exact same reduction in exhaust back pressure over the stock secondary cat system, as the Supersprint "J-Pipe" is a monsterous 100mm / 4" proprietary design bent pipe section, hydro formed to oval, which equals our 70mm twin pipes in terms of combined cross section.

No less important, the Supersprint J-pipe while being huge in diameter, ensures stock-like ground clearance in all places.
