I have for sale a used Tanabe Concept G Medallion cat-back exhaust (N1 style) for 2006 2007 2008 2009 2010 2011 Honda Civic.
This will definitely fit the coupe but you may need a spacer/adapter to fit the sedan as the sedan's chassis is longer or maybe not?
This is for the non-Si (so R18 - DX. LX, EX) but just the axleback will definitely fit the Si. However, at the moment I am not parting out just the axleback.
Specs
Tip diameter: 100mm
Pipe diameter: 60mm
Made of stainless steel. Mandrel bent. Made in Japan.
Condition: Excellent condition (barely noticeable scratches from wear and tear) and I keep the axleback clean.
The exhaust isn't that loud until you hit about 2800+ rpm which is where you can probably hear the nice, deep and "hallow" tone.
Asking 350 for the entire exhaust system. I will also include the bolts and nuts as well.
Pm or call/text 604 376 3120.
