Tanabe Concept G exhaust regular price $390. Found on Ebay for $250 plus $50 shipping. Excellent exhaust for a bolt on axle back muffler.. Made my 2006 civic si deeper and louder. IF your looking for a good sounding, not obnoxiously loud exhaust, then i recommend this to you..plus it make for a little eye candy. looks good on the car..Sounds real good when u step on the gas.
