How to V-Mod your exhaust

Information

• The standard muffler has 2 baffles, and inner
  (show) and an outer (to be kept intact, not
  shown)
• The inner baffle is welded into the muffler at
  both ends.
• This mod will deal with how to remove only the
  inner baffle from the STOCK muffler.

• Step 1 exhaust end

• Remove mufflers
• Insert in vice. Wrap with soft cloth to protect
  chrome body.
• Start at exhaust end.
• Use a steel hole cutter 3 size, with a wooden
  dowel fitted as shown. Insert dowel into the hole
  at exhaust end. (it will keep cutter centred.)

Information

• The cut is not deep, simply until you are through
  the back plate of your muffler.
• The dowel fits inside the exit hole to keep
  cutter in the centre.

Information

• The reason for the drilled holes is to eventually
  allow the exit of the whole baffle out of the
  hole you are creating.
• The baffle is wider than the hole you are making
  so it will later be made bigger using a die
  grinder or dremmel tool.

Step 2 header end

• On the header side of the muffler, use a 1 ¾
  hole cutter to cut through the weld where the
  inner baffle is attached to this end.
• Consider using a wood dowel on the end on the 1
  ¾ hole cutter to keep it centred. See below.
• The cut will be relatively shallow before the
  baffle is freed.

Information

• This is where the inner baffle was cut out using
  the hole saw.

Step 3 exhaust end

• The hole may have to be widened to allow the
  removal of the inner baffle.
• Consider using a dremel and then dressing hole
  with a metal file until you get the desired oval
  shape.
• Note WARNING the outer baffle is close to where
  you are working DO NOT damage it.

  oval shape that follows the line of the outer
