I used to own a street legal remus exhaust on my EK civic. But Remus did not bring in cat converters and extractors before so i bought third party extractors from fong kim but lost alot of power on the high end and drinks too much. The Remus exhaust have a very low hum and sounded very nice. after a couple months, they started sounding even louder.
i think HKS has a complete system available if you wanna change whole exhaust. Friend did a full system from Garage R for his car. He is very happy. Not to sure about the performance gain though.
Might try change my exhaust system as well when my new car is ready.
