Its just single sided but it does eliminate the middle resonator muffler like I did.
If its any comfort cappa, I have modified the exhaust on every car I have owned. 1992 5.0 mustang, 2002 Subaru WRX, 2005 BMW Z-4, 2006 Infiniti G35, 2009 Toyota Tacoma. The Subaru was at the dealer, The Tacoma was at the dealer. I would not worry about the exhaust unless you mess with the cats.
