Specifications and Features:

• Everything you need to make a great 4" downpipe for your turbo setup, just supply your own 4" pipe!
• Starting with the cast ARTEC Turbo Exhaust Outlet Flange. Choose between the G3 Flange (for Garrett G25 - G35 Turbine Housings), or the G4 Flange (for Garrett G40 - G45 Turbine Housings). These make the transition from your turbo outlet to 4" pipe a breeze.
• Our cast saddled O2 sensor bung is shaped to perfectly match the curved surface of a 4" pipe so you can place it anywhere you need with ease. With machined M18×1.5 threads, it's compatible with almost all O2 sensors. 
• A second cast saddled 4" mount, 90 degree fork and 180 degree fork serve as the basis for making a solid bracing setup. Use any combination of the three with 10mm rod to fabricate a brace for your turbo and manifold setup. 
• A 4" Stainless Flex Joint minimises risk of cracks in the rest of the exhaust system. We've made sure that this flex joint actually compresses, expands, and flexes unlike some other options on the market.
• The final piece of the puzzle is the 4" V-Band Flange and Clamp. Use this to connect back to an existing 4" V-Band exhaust or begin fabricating the rest of the system from here.
