Removal of Stock System:
1. Apply a penetrating lubricant liberally to all exhaust fasteners, hangers and rubber insulators.
2. Loosen the nut on the band clamp located behind the catalytic converter
using a 15mm wrench or socket. See Figure 1.
3. Remove the muffler and tail pipe from the OEM rubber hangers. To
remove the system in one piece, on 03-04 models, the bottom shock bolt
of the passenger side shock must be removed. This is not required on
05 or 06 models. Separate the stock exhaust at the slip joint located

behind the catalytic converter and remove the muffler and tail pipe from
under the truck. Re-install the bottom shock bolt.
4. Remove the catalytic converter by removing the two nuts holding the inlet
flange together using a 15mm wrench or socket. Retain the nuts for the
re-installation of the catalytic converter. See Figure 2.

(Note: The stock down pipe can be removed in one piece by removing the
transmission cross member. MBRP Inc. recommends that this procedure
only be done by qualified, trained professionals using tools and equipment
designed to safely carry out this process.)
