Like all Flowmaster systems the pipes are all mandrel bent to reduce any restrictions and maximize performance. The system finishes with 2.50" polished 304S stainless steel tips that exit within the factory cutout bezels. The exhaust system is manufactured in the USA and is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation.
