Single Sided to Two Sided Exhaust on Standard Model

[Ron in MO_imp]

I have converted the single exhaust on my 2013 CB1100 to a 4 into 2 system, using used header pipes from a forum member's 2014 DLX model and aftermarket Over Racing slip-on mufflers.

The removal of the old system was simple. Just make sure that the exhaust header gaskets come out of the exhaust ports. I would also purchase and install fresh exhaust gaskets if they don't come with your new system. You can also use a small amount of high temperature gasket sealer to hold the new gaskets in place up in the exhaust ports while you are positioning and bolting in the new headers.

You will also notice that the right muffler attaches to a mounting point on the rear of the right foot peg bracket. Since I was using a system meant for the 2014 models, I had to purchase the left foot peg bracket from Honda that is used on the DLX models. It had the same muffler mounting point that the right one has. If you are purchasing a 4 into 2 system that is being sold for the 2013 model, it may have a different left muffler mounting bracket than using the DLX foot peg bracket.

One other challenge I ran into was that the 2014 DLX left side exhaust header uses a frame mounting point that is not on the 2013 or 2014 Standard models. I used a long bolt with a large rubber grommet with washers on each side that rests on the frame just in front of the shift lever shaft. It really worked well, once the whole system was in place.

Other than these issues, the install was pretty easy. Here is the link to my post on the swap I did. Good luck and let us know how the install goes for you. Pictures are also nice!
