RENAULT CLIO SPORT
2.0ltr 124kw
2001 to 2004

This factory cat will flow as good as, if not better than most hiflow cats, the only problem you may have with the factory cat is cracking on the inlet [move over image]
a quick weld and its as good as new

The engine ecu analyses the exhaust gasses before and after the catalytic converter
via oxygen sensors, most aftermarket catalytic converters dont reduce the exhaust emissions to satisfactory levels to give correct readings, this can cause the
engine to run lean

After the remus muffler is fitted the only restriction after the cat if any would be in the centre muffler , this car will be returning in the next few weeks for a replacement centre section, we looking to stop the cracking sound [resonator cooling] and to see if replacing the centre section will give a power increase without loosing torque,
no point gaining top end Kw if
you loose low end Kw

The Remus muffler
sounds as good as it looks
