MBRP S6218 - Manual (Page 2)

Removal of stock FORD system:
1. Loosen the nut on the band clamp located behind the catalytic converter.
2. Remove the muffler and tail pipe from the OEM rubber hangers. Separate the stock exhaust at the
slip joint located behind the catalytic converter and remove the muffler and tail pipe from under the
truck.
3. Remove the catalytic converter by removing the two nuts holding the inlet flange together.
4. From underneath the vehicle cut the factory down pipe as high as can be reached safely. Again cut
the down pipe from above, as far from the turbocharger as safely possible. Remove the remaining
piece of the down pipe from the turbo by removing the band clamp. Retain the band clamp for the
installation of the new down pipe.
Installation of MBRP Inc. Performance Exhaust:
1. Install the Down Pipe in the same position as the stock down pipe. You will need to create room for
this Down Pipe by bending back the pinch weld connecting the firewall to the floor in the area
where the Down Pipe will pass through. Make sure that there is adequate clearance around the
Down Pipe so that there will not be any interference after the Down Pipe is installed. Connect the
flared end of the Down Pipe to the turbo using the stock band clamp. Do not fully tighten until all
components are in place.
2. Attach the Mid Pipe to the Down Pipe using the 3” Clamp supplied to secure the slip joint. Install
the Hanger Clamp into the rubber insulator previously used for the catalytic converter and secure
to the Mid Pipe.
3. Hang the “T” Hanger Clamp in the factory rubber insulators. The insulators are located right above
where the rear of the factory muffler was located.
4. Temporarily install the Muffler in place and measure from the front of the Muffler to the Mid Pipe.
This will give you the required length to cut the Extension Pipe.
5. Cut the Extension Pipe to the required length. Attach the Extension Pipe to the Mid Pipe. Place
the Hanger Clamp into the rubber insulator located on the frame beside this joint and loosely install
around the slip joint.
6. Install the Muffler over the Extension Pipe and loosely install the “T”
Hanger Clamp over the end of the Muffler. Place the remaining Hanger
Clamp into the rubber insulator located on the frame beside this joint and
loosely install around slip joint.
