About these parts
Check your model year before ordering C6 exhaust. Fitment splits at 2009 — 2005–2008 and 2009–2013 systems are not interchangeable despite both being C6 cars.
Akrapovic offers a stainless Slip-On Line for the 2006–2013 Z06 and ZR1 and a stainless Evolution Line cat-back for 2006–2011. Both require tips, which are sold separately.
The difference between the two: a Slip-On replaces the rear muffler section only, while an Evolution Line cat-back replaces everything behind the catalytic converters and changes tone more substantially.
