Full Pipe Gut

The full gut is all the insides cleaned out - - easier to do with a slash cut -(unless your a Proctologist - or an OB-GYN - then go right ahead and get all that stuff outa that tiny little hole...LOL) - something to use as a chisel for the welds - long thin - sharp with a spaded end - (tire iron - sharpened re-bar)- really helps - and a dremel tool - gotta have a dremel tool - - big - big help....

I used a chop saw or miter saw with a metal blade for the initial slash cut ..... local muffler shop did it for free...Locate the position and angle of the cut and mark the cut line on the muffler using a felt tip pen. Wrap the entire cut line with wide masking tape to prevent the chrome from chipping while the initial cut is made, however the chrome does actually hold up very well when the muffler is cut. If going the machine shop route or muffler shop for the cut, I recommend protecting the chrome finish with wide masking tape. This will help to keep the finish from getting scratched while clamped in the band saw. You may also want to take a couple of blocks of soft wood to place in the jaws of the clamp, to further protect the finish.

After the slash cut just use the long chisel to pound holes in the baffles till you can pull everything out (great way to get rid of a lot of pent up aggression.... very therapeutic) - then use the dremel with a heavy duty cut-off wheel to clean up - I warn you this is loud - all the car alarms will go off - trust me...(grin)....

I left the double body wall in - I like the look

To remove the Double Body Wall use the Dremel, again, to carefully cut it out around the entire perimeter of the muffler. Leave about a 3/4" width ring of the double wall in the muffler. This 'ring' is spot welded to the Second Baffle Plate in four places and will have to be removed one section at a time since you can't get to the welds to grind or cut them away. Be careful when cutting out the double wall. If you cut into or grind the main muffler wall it will be noticeable when you're done, especially if you paint the inside with aluminum instead of black.

To remove the double wall ring, first make a very sharp chisel out of an old flat blade screwdriver. Grind the flat blade to a sharp edge with the Dremel tool using the flat side of a cut off wheel. The spot welds holding the wall to the baffle plate are evenly spaced at 90 degree intervals around the perimeter of the ring. The diagram above shows the spot welds but the exact orientation may differ from muffler to muffler. The diagram is for illustration purposes only and is not in scale detail. Notice that the 'Cut Here' mark is located exactly between two of the spot weld positions. Use the chisel, starting on the ring's edge and between two of the spot welds, to cut the ring from the outside edge down to the baffle plate. Cut the ring in four places so that you have four large tabs, each held in place to the baffle plate by the spot weld at the bottom center of each tab. Grab each tab in turn with needle nose vise grips, and wiggle back and forth until the tab breaks off at the spot weld. What you should be left with is four barely noticeable spot welds on the baffle plate. Be careful when cutting the ring with the chisel that you don't cut or gouge the main muffler wall.

I have people ask me about my pipes all the time ....("wow...where did you get those pipes.. they sound great") - and all they cost was sweat....(LOL)..... why spend $400
