Tanabe Medalion Concept G Blue Full Turboback Exhaust
Pros
The Tanabe Concept G Blue exhaust has been the hottest item among Mitsubishi EVO owners since its U.S. arrival early this year and for obvious reasons. Designed by Tanabe engineers, the Concept G Blue system sports a full turbo-back exhaust system using SUS304 80mm stainless steel piping and an esthetically appealing 100mm Inconel flame treated tip in a blue hue. What makes this exhaust system such a hit among EVO owners is the included 70mm downpipe and optional test pipe that deletes the secondary catalytic for off-road use only. If you're looking for the ultimate in free-flow exhaust systems with a big horsepower increase, look no further.
Cons
If removing the under tray and plastic paneling off the EVO to access the factory downpipe wasn't such a pain in the ass, we would have finished installing and testing the exhaust long before the sun decided to set in wonderful smelling Riverside. Since were on a gripe fest here...could there be any more plastic clips to remove from the undercarriage Mitsubishi?

Notes
The advantages of installing the Tanabe exhaust brought a mischievous grin to our faces when the dyno wheels came to a screeching halt. With gains of 35hp and 27 lb-ft of torque over our baseline run, we called the obvious notion that this EVO was just begging to extract more horsepower from the factory. Peak gains were recorded at 24hp over our previous K&N filter run. Be wary that this exhaust isn't for the faint of heart. The exhaust tone that emits from the canister is loud enough to wake the dead! Although... you can always pussy out and use the silencer.
