CONSTRUCTION
The ARM 135i catless downpipes are designed with a 3" stainless steel construction to optimize exhaust flow and obtain optimal back-pressure. Each downpipe has 2x O2 sensor bungs so the factory BMW O2 sensors can be remounted, allowing the ECU to continue to monitor the exhaust gases. Because these downpipes are a catless design, an ECU tune or CEL fix will be needed to avoid a CEL from displaying on instrument panel.IN THE BOX

Quality and affordable Swiss chronometer.
Color: Silver
This is a basic but certified accurate watch which is what I wanted. It is a very good looking watch and shows quality at every level.
I have had it for seven days now and it has gained between 7 or 8 seconds which exceeds the certification standard. If it maintains this level of accuracy it will far exceed my expectations.
