Supersprint has been the exhaust supplier for Hartge, since the early 1980's.

We had developed tubular headers and performance, full exhausts for all of the M30 engines, in all of their versions; bore and stroked, higher compression, camshaft tuned.
The Supersprint / Hartge exhausts have made history, with the E28 H5 having become an iconic model.
Now 35 years later, we still offer these same exhausts, handbuilt individually to their original design specifications, at our Factory in Mantova Italy.
No E28 classic /restoration project car is complete without a Supersprint exhaust in place.
