4. The front pipe also has a hanger mounted to the transmission that will
also have to be removed. Figure 4 shows the front pipe assembly
removed.
5. The heat shield on top of the turbo will need to be removed. There is
also a shield on the back of the down pipe. It runs along the firewall
that needs to be removed. The 2 stock sensors on the top of the down
pipe need to be carefully removed. Set the sensors aside and save for
the installation. The stock V-Band clamp can be removed save for the
installation. From the underside of the vehicle carefully slide the stock
down pipe out between the frame and transmission.
Installation of MBRP Exhaust Component
1. Start the install by sliding the Down Pipe up from the underside of the
vehicle or the passenger side wheel well. Mate the flange up to the
turbo and install the V-Band clamp at the turbo. Leave the clamp loose
enough for some rotation.
2. Loosely securing the Down Pipe to the exhaust manifold with the hex
bolt from the stock down pipe. Finish tightening the V-Band at the
turbo and then finish tightening the bolt on the exhaust manifold.
3. Install the stock sensors into the Down Pipe. One is located along the
lower section of the Down Pipe (Refer to Figure 8.) The other two
sensors are located closer to the turbo.
4. The front pipe can then be reinstalled using the stock hardware and V-
Band clamp. Refer to Figures 8 & 9.
