DEP 2 stroke pipes are produced from high quality CR1 grade, mild steel material. Ranging from 0.9-1.2mm, depending on the model and purpose. The 2 stroke stampings are produced through our own deep drawer process, using CNC cylinder mounts, in-house laser cut mounting brackets and fabricated with high quality TIG and MIG welding. All models are available in the bare metal factory finish and nickel finish. Our 2 stroke pipes have been designed to improve performance over the OE pipe with in-house DYNO and track testing.
