Have a nice bolt on package for c7 z06. Package includes borla atak rear exhaust part # 11905. This retains factory npp valve feature. Also included highly desirable borla x pipe part # 60547 which they no longer manufacture. Lastly aFe momentum cold air intake with dual filters. Everything came off my 18 z06 and is in excellent condition. Want to sell as a package. $3400.
