Installation Instructions for 30375 Muffler Kit

Fits: 2009-2013 Dodge Ram 1500 with 5.7L V8, 2WD & 4WD, 120.5”, 140.5”, 160.5” wheelbases, for vehicles with factory dual exhaust only.


Note: this kit fits only vehicles with factory dual exhaust. You will need to reuse all original parts including the front extension pipe, tailpipes, tips, and hangers. This kit only includes a new performance muffler and parts necessary to install it to the factory front extension pipe and the factory tail pipes.

1) Remove the exhaust system at the clamp at the muffler inlet, leaving only the original y pipe, rubber hanger mounts, catalytic converters, o.e. front extension pipe, and tail pipes on the truck. You may need to use a lubricant to remove the wire hangers from the o.e. rubber hanger mounts.

2) The 3” S-Bend extension pipe will fit all wheel base trucks without cutting. Install the new 3” S-Bend extension pipe to the o.e. front extension pipe using a 3” clamp. The S-Bend extension pipe will raise up to the muffler inlet.

3) Install the muffler to the S-Bend extension pipe using a 3" muffler clamp to attach the inlet of the muffler and the S-Bend extension pipe together. NOTE: The muffler will need to be installed at an angle, and not with the flat side parallel to the ground. The driver side of the muffler should be at approximately a 10:00 position (so above the driveshaft), and the passenger side at approximately a 4:00 position (below the drive shaft).

4) Install the driver side tail pipe to the driver side outlet of the muffler using the included 2-1/4” left hanger clamp.Attach the wire rod to the o.e. mount above.

5) Install the passenger side tail pipe to the passenger side outlet of the muffler using the included 2-1/4” right hanger clamp. Attach the wire rod to the o.e. mount above.

6) Tighten all clamps and bolts and check for clearance of the frame, body, and brake and fuel lines. You can snap the ground at the muffler outlet to the hanger on the passenger side rear outlet.
