I am wondering if I were to remove the Silencer out of my Yoshimura TRC Carbon Fiber pipe, what would be the overall result, besides increase in sound? :_confused1:
i called yoshimura directly and spoke with one of their technical experts and they said that removing the silencer would not affect gas mileage or performance - only the level of sound.
so....i initiated, facilitated, and completed the task of removing the silencer out of my Yoshi TRC Carbon Fiber Exhaust. it took about an hour from start to finish. not bad at all, for an increase in presence awareness.
keep me posted on what you decide and the outcome as well.
hope this helps!!!
NOTE: if you should decide to remove the silencer, let me know and i can share with you a few additional points to review, prior to beginning the project.
Well, i decided to take this adventure on tonight with my TRC slipons...
When i put the "stock" yoshis on out of the box, it was no where near the sound i was wanting. So removing the silencer was a must. It wasn't that hard after i got the first one done and figured out the trick. I believe i am going to get a Y-Pipe and remove the cat to get the sound im really looking for.
Tips:
Drill all the rivet heads out.
Knock all the centers out of the rivets.
Drill the rest of the rivet out.
-- Doing it in that order took less time for me.
Cut the grey sealant, what a pain..
Pull the end cap off, take out the allen screw.
Pull the silencer out with pliers.
Pull the baffle off to get the all the rivet pieces out of the can.
-- WARNING, this could cause you issues getting the packing lined back up, it was a risk i was willing to take to get the rivets out. I had no issue putting the baffles back on.
Put baffle back on, put endcap back on, re-rivet (3/16's), re-install pipes, rever' up.

i am glad things worked out for you as well.
you mentioned about your pulling the baffle off to remove the rivet pieces in the can!?! help me on this one please. baffle being where? inside the tube?
for me, i did not remove the rivet pieces as from what i've heard, they just get wedged into the insulation and packing and are no issue at all, but i am interested in what you did specifically. got any pics of the baffle?
I am referring to the piece in the end of the can the silencer sits in. I was not going to risk having the rattle of 8 rivets in there, so i took them out.
Im not saying anyone has to, just that i did.
If you look at the link above, it has pictures. In the picture where he is pulling the silencer out with the pliers, the piece i am referring to is in that picture.

got ya! i am not hearing any rattling so far, but that is good to know.
one more thought. if you end up removing the cat, you will definitely see a decrease in gas mileage and performance.
I took the advice for the forum on removing the silencer; I simply removed the pipe by detaching the two springs and removing the allen screw, after that I took a broom and push the silencer out ( it was that simply- took 4 minutes). It is my understanding that you have to remove the rivets only on the carbon fiber model. The sound is much better without the silencer.
Would the same method apply to the TRS carbon pipe as well? I am looking for a better sound from my Yosh pipe too. I was originally going to cut down the silencer but I dont like the look of the TRS shortys with the standard endcaps. Removing the silencer is a great alternative to me. Below is a pic of the the TRS muffler I have..the one with the long name plate. I searched by could not find any info for the TRS.
Lastly, this may be a silly question but which part is the baffle? Is is the perforated metal tube inside the muffler? Any pics of one? The guide mentioned in an earlier post kinda skips pictures where the baffle is removed.

can you email me a picture of the open-ended view of the exhaust? i cannot tell from the picture you attached how it may be designed, but i am willing to try.
well worth the time
