Dear Bipolar-Exhaust friends,
We would like to make an important announcement: Since the summer of 2022, our products have been 100% owned by Grail Automotive GmbH. From the beginning, our products have been and will be produced by Grail , and the name"Bipolar" will gradually be retired.
We would like to point out that our products continue to offer the same consistent quality. Your satisfaction is still our top priority.
From now on you can reach us at the new e-mail address: info@grail-automotive.de
