181-00121 LAPTORR Exhaust System E46M for E46-M3

181-00121-E46M
Exhaust System E46M

Overview
We’ve completely redesigned the system to improve performance following the model refresh.
The layout starts from behind the exhaust manifold.
By eliminating the catalytic converter and ensuring the two front pipes are of equal length at the optimal position before merging into a single pipe, we’ve improved exhaust efficiency and achieved a very clear high-frequency exhaust note.
The single finisher has been repositioned to look stylish from the bumper.
A dedicated rear diffuser is currently in development and will be released at a later date.
