Intruder Silenser
« on: March 14, 2015, 06:28:21 PM »
Is there any markings on the silencers so I know what I have on my Intruder?
I have two with small differences  :P

I do not have them at home now so I can photograph them  :-\
Are they labeled with part numbers?

They are not marked with part numbers. 

I'm not sure about the Intruders, but I know that the 80' & 81' Invaders had a different pipe than the 78' & 79' Invaders.  the newer version is larger and has an extra chamber before the tail pipe.  Where as the earlier pipe is smaller and has a longer tail pipe.

This is how the silencer looks out that I have mounted at the moment.
I have one more but I can not take the picture right now

Nice sled,  the muffler looks like it was meant for that spot.  I'd run it.

 VERY nice sled!  Looks like a 78-79 version pipe. 

That chain case cover looks familiar.  ;)

 I have the pipe out of my 79 Invader 440 for some fresh paint..and your pipe sure looks identical to mine.
 I don't own an Intruder, but I know they used a pipe with a different part #.
 With the Intruder having a power peak roughly 1000 RPMs lower than the Invader, I would have thought there would be some visible differences in the length of the various sections of the pipes.
 Anyone on here have any pictures of the Intruder pipe?

These pipes are a pipe and silencer built into one.  Inside of the pipe is a divergent cone (I think this is what they are called), I believe that some of the tuning of the pipe is dictated by where the cone is located inside of the pipe.  It's possible that they look identical on the outside, but have the cone in a different location on the inside.  The easier way is to find the parts books and compare the part numbers.

 Yep, they may look identical, externally. I know the exhaust y-pipe has the part # stamped into it. Does the tuned pipe? I sure don't remember ever seeing anything stamped in mine.
 It may be tough for Habbeli to ever know for sure. ???

 I found the part # stamped in my pipe. Habbeli, if you can still see the numbers on your pipes, we can tell you exactly what you have. 8)
  78-79-80 Intruders used pipe 39083-3502.
 81 Intruder used 39083-3513.
 Don't have info for the 82, but I would guess it used 3513, also.
