Yesterday, I heard a rattling sound coming from under the car and had it checked out. It sounded like rocks in a can. turned out to be the CATS (both of them) ceramic interior had broken up to bits and were rattling inside. The exhaust flange near the CATS were also cracked. A replacemnt from the agent will cost about B$1200 each with labour costs included. Where I live there are no emission laws, as long as I dont turn the car's stock exhaust into a potato cannon and sound like thunder on wheels. The benefits would be more power (?), mileage (?) and most probably a different exhaust note from the engine. What is everyone's opinion on this? If its cheaper to import a brand new Pacemaker extractor and single tuned sports exhaust system from them, then this will be my next project.
