The dAHLer Sound-Plus-Kit for the stock exhaust of the BMW M3 G80 and G81 and M4 G82, G83 and CS will boost the sound of your stock exhaust up to 9 DB.

This bespoke H-pipe in conjunction with dAHLer’s Valve Controller unlocks a superior tone out of the stock exhaust system and enhances the burbles in Sport Plus Mode. You will hear a noticeable difference in sound but it will still be perfectly liveable for daily driving!

This is a great first mod on anyone’s journey in the aftermarket world and for those who are unsure about a complete new exhaust system.

Made from high quality stainless steel in a compact size this Sound-Plus-Kit can be easily shipped worldwide.

True to the motto: Exact like a Swiss clockwork, the dAHLer Sound-Plus-Kit meets the highest demands in optics and fitting accuracy. It is extremely lightweight at maximum strength, weighing only 6.4 kg (12.8 lbs)

The installation time is approximately 2 hours and the new sound of your stock M car with the dAHLer Sound-Plus-Kit underlines the high-tech character of your M.  While it is possible to install this part on your own, it is highly recommended that you use a professional. dAHLer will not be responsible for poor installation practices. We recommend having the assembly carried out by a professional car workshop or BMW dealership.
