If you have a 2002 and probably up Monster your pipes are not like those shown on Ducati suite. I went to core my pipes today and found out that there is no baffling inside at all. It has a honeycomb thing in the bottom of the pipe that goes into two pipes. One small one big. The small pipe feeds into a chamber which has another pipe that feeds through the second wall with the larger pipe mentioned before. I cut my pipes down to 9 1/2 inches from the back of the aluminum shell to the front. I don't know if this will give me the desired affect, but we will see.

Just in case, does any body have a set up stock pipes they are willing to let go. If so PM me. Thanks...

the "honeycomb" thing is the catalyctic converter.

to clear up some confusion...
the honeycomb thing isn't a cat. the cat on '03 models is actually located in the inlet portion of the muffler, prior to the "body". what andrew's referring to is in the 3rd chamber of the '01+ exhaust, there's a section of insulation (for heat/sound) lining the perimeter of the muffler body. it's held in place by a layer of perforated sheetmetal.
andrew, your muffler definately has baffles. but in '01, the design changed from that depicted on ducatisuite.com to move them further up the muffler body to get the weight more forward. don't worry though, by hacking up the guts of the can, you bypassed the baffling system. you don't necessarily need to gut out the innards.

i thought Andrew was referring to the structure at the inlet. sorry for any confusion.

I was referring to the inlet from the header pipe to the main body of the can. That is where the honeycomb part is. I hacked my pipe down to 9 1/2 inches long and there was no stuff in side. After removing the aluminum can I has a stainless steel outer shell rapped around carbon fiber. Inside I had two walls welded into place to make three chambers. Inside there was three pipes. Two of these pipes just connected one chamber to the other and one ran all the way out. Once I cut pass the first wall, I then hand only two pipes. One big and one small, both of which ran directly to the honeycomb piece at the inlet of the pipe.


I checked and there was no packing what so ever.

I have a 2002 as well, and when I cored out my pipes there was alot of packing. I used a stainless steel hole saw and cut out two baffles from the end of the pipe and pulled out a sh*tload of packing then I used a dremel tool and cut about 4~5 inches of the small inner pipe out. Sounds Great!!
