181-00121 LAPTORR Exhaust System E46M for E46-M3

181-00121-E46M
Exhaust System E46M

Overview
We have significantly redesigned the system to improve performance following the model refresh.
The layout starts from behind the exhaust manifold.
By eliminating the catalytic converter and aligning the two front pipes to equal length at the optimal position before merging them into a single pipe, we have 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 under development and will be released at a later date.
