Exhaust Turbo Elbow Outlet Pipe SR20DET

• 1989–1998 Nissan | 240SX

The Tomei EXPREME turbine outlet pipe (TB6020-NS08C) replaces the restrictive factory turbo elbow on Nissan SR20DET engines with a single-piece, lost-wax-cast SUS304 stainless steel design for greater exhaust flow, faster turbo spool, and reduced exhaust back pressure. The revised design delivers 920cc of volume with smooth, step-free inner walls, an optimized turbo-side port, and an enlarged 70mm (2.76") front-pipe-side exit — a direct bolt-on for SR20DET S13, S14, and S15 platforms.
