Dinan Free Flow Axleback Exhaust - Black Tips - BMW F30 / F32 328i / 428i

The Dinan Free Flow Axleback Exhaust for the BMW F30 328i and F32 428i reduces exhaust back pressure for a measured gain of +4 HP and +3 lb-ft of torque at 6600 RPM, while incorporating drone abatement technology that keeps the cabin refined at low RPM. The system uses the factory brackets and hangers for direct bolt-on fitment and exits through twin 70mm ceramic black-coated tips with laser-engraved Dinan branding. At higher RPM and under load, the character shifts from subdued to pleasantly aggressive.
