The owner of this Peugeot RCZ with the 2.0 163 bhp HDI engine recently contacted us enquiring about a service, our CustomPro remap software and an upgrade to the exhaust system. After searching online he found the Zunsport quad tailpipe was exactly what he wanted, so we went ahead with that.
After replacing the oil filter and air filter with a fresh oil change, we installed the tailpipe assembly as pictured below. It took it from the standard dual exit one one side, to the much cleaner, more symmetrical quad.
With the exhaust system fitted, we concentrated on our CustomPro remap software. As you can see by the graph below, the car made good standard figures at 157 bhp and 274 ftlb of torque. Once complete, the graph was perfectly smooth with a consistent improvement throughout the rpm range.
Power gained: 30 bhp
Torque gained: 34 ftlb
