Description
The R1TITAN EXTRA STTI for BMW E92 M3 is a newly designed muffler exclusively for the E92.
The layout has been significantly changed to use four silencers to silence the exhaust without throttling it, improving power output and enjoying the NA sound of the M3.
No welding is required as it can be connected to the original flange.
In addition, it is possible to change to a full titanium exhaust from the front by combining it with the R1TITAN front catalyzer and R1TITAN front pipe.
