OP, see my sig for a real sound clip of the Tanabe Concept G Blue.

I love it.

Sounds like a V8 at WOT above 3500 RPM.

Nice and humble when just cruising around.

 

whats the true diameter of the pipeing?

 

I have this exhaust system installed nice deep tone looks great just a little loud on the freeway other than that very good exhaust!

 

Anyone?

 

On Tanabe Medallion Touring, is it 3" from DP to catback?

 

Most if not all JDM DPs are not 3", more like 2.75" but the exh. section is 3" after a very slight taper (about a mm or so)...

 

I have the concept G blue on my evo 9 se. I love it and looked into many different systems. I have the turbo back with cat delete pipe. It is very loud getting on the throttle from half to full throtle. If your concerned at all with how loud it is i would use the incert and run your cat to keep the noise level down. This system is beautiful and has a great unique sound to it. Very high quality and built 100% in house in japan.
