TiAL 44mm External Wastegate. V44 Perfect for built Turbo Charged Engines. The perfect wastegate needed for the hardcore turbo kit. Its higher cost is well worth the quailty, construction, and ease of use packed into this unit. The V-Band clamps make positioning the gate and dump in the perfect location easy. The flanges do come with this wastegate. Remember by picking a spring pressure you will run really close to that psi. You cant go under that pressure only above it. So a .5bar spring in a 44mm will run about 7psi, you can then install a boost controller to up the boost to 10psi. You will not be able to go under 7psi unless you change the spring. Colors not stocked. Usually pick the spring close to the boost you want to run. ***COLORS FREE***
