I was looking for more info for the exhaust systems thread. The following info comes from G-Power's website.
G-POWER Exhaust Systems
Always the right "DEEPTONE"
After they get past the paragraphs of patting themselves on the back for making such an amazing product...
-100% stainless steel
-Made in Germany
-On request: "Medium Sound"-version for export only
They DO make an exhaust specifically for sedans.
