    Tial MV-R Wastegate 44mm Blue w/ All Springs ( Part Number: MVRB)
    Amazing! 2 years ago

    Best decision I've ever made. This along with the dump tube is just awesome, don't be scared that it's gonna sound bad or be too loud because it's perfect. Everyone will think your car is like 1000awhp when they hear it lol Install was super easy as well. Just be sure to set the spring rate right!

      Is it easy to swap springs ones External Waste gate is under the hood? Planning to hop the car to tuner after EWG is installed. Just wondering just incase the tuner have to change springs.

        A:  The cap needs to be removed in order to change the springs and where the EWG is located will affect how difficult it is to access the cap.
