PRL's front pipe is constructed of mandrel bent 16 gauge 304 stainless tubing and 304 stainless 3D CNC'd flanges with smooth transitions for optimal flow and fitment. All pieces are fully back-purged for weld integrity and optimal strength while the front pipe features a high quality, reinforced stainless flex section.  Flanges are machined and welded in house. Customers can run an aftermarket exhaust or mate our combo to the factory exhaust.
