Veefer800Canuck Posted September 15, 2008 Share Posted September 15, 2008 I think someone drew one up in PAINT. IIRC, it was in one of the MANY "exhaust gut" threads for the 6th gen......... (n I ain't going looking for it, sry!) Link to comment Share on other sites More sharing options...

Member Contributer Lobster Posted September 18, 2008 Member Contributer Share Posted September 18, 2008 It's been a long time since I've gutted one so I'll try to talk to through it. Three chambers. The exhaust passes a screen into the first chamber (closest to the front of the bike), then through a pipe to the third chamber (closest to the rear), then turns 180 and goes into the middle chamber, then turns 180 again and out the actual pipe you see coming out the end of he stock can. No pic, but I hope this helps. PM Kanadian Ken as I think he might have a diagram. Link to comment Share on other sites More sharing options...
Member Contributer sckego Posted September 18, 2008 Member Contributer Share Posted September 18, 2008 Find the exhaust gut thread started by Rice. He had a great diagram of what it looks like. Link to comment Share on other sites More sharing options...

KanadianKen Posted September 25, 2008 Share Posted September 25, 2008 hope some of those helped, its all I've got. I'll be gutting another one this winter - I'll take some better pics then. Link to comment Share on other sites More sharing options...

Guest Posted September 30, 2008 Share Posted September 30, 2008 when people drill them out what part are they drilling??? i know you just basically shove a long drill bit into the exit pipes and drill away...is there a better or easier way to do it...???

Got the same question. Please any one knows put some mark-up on the diagram showing where to drill, how deep and actually the modification hole would be made from which part to which parts? Thank you. Link to comment Share on other sites More sharing options...
CandyRedRC46 Posted August 20, 2011 Share Posted August 20, 2011 you dont drill these mufflers. just cut off the ends, pull the 2 exit pipes out, then re weld the endcaps back on. Link to comment Share on other sites More sharing options...

What you're actually doing is removing a small section of the last exhaust pipe so that the air, rather than flowing back into the middle chamber and out, can go directly from the first chamber out. You are removing this section in the circles, and the arrows show the airflow. There is a step-by-step instructional thread, but basically, you drill out the weld that holds the exit pipes in place by drilling with a 1" whole saw around the outside of the pipe, then with a small cut-off wheel, you cut the exit pipe from the inside and pull it out.

VietHorse Posted August 20, 2011 Share Posted August 20, 2011 Thanks Ryan for the obvious explanation. That way is more on gutting the muffler. In HERE, they mentioned about "drill" some holes "at the angle"... and I believe that is drilling on the muffler. There is a diagram showing the "drilling" on other bike exhaust: Link to comment Share on other sites More sharing options...
Baileyrock Posted August 20, 2011 Share Posted August 20, 2011 yeah i figured someone would have done that...i looked through a ton of the threads and still have not seen it...if anyone is more familiar with the thread or if you were the one that made the sketch can you please post here...thanks Use Google search, it works a lot better than ours IMO! Just add ,VFRD to the end of the search and it pulls things up nicely! ie: "Gutt 6th gen VFR exhaust, VFRD" BR Link to comment Share on other sites More sharing options...

There is a diagram showing the "drilling" on other bike exhaust: No, I am referring to the "no gut" solution. So that we're all on the same page, and not arguing over definitions: Gutting the muffler involves sawing off the end caps, removing everything, and then reattaching them. What I'm referring to is removing a small section of the outflow pipe by drilling into the muffler and using a dremel. Here is the original thread: "New Way to Gut" thread Is this what you're asking about? Link to comment Share on other sites More sharing options...

Just add ,VFRD to the end of the search and it pulls things up nicely! ie: "Gutt 6th gen VFR exhaust, VFRD" BR I agree, use Google to search this site. But the correct way to search and get only VFRD info is to use this search format - "Gut 6th gen VFR exhaust site:vfrdiscussion.com" Use the "site: ~~~~" to limit your results to just one web site.
