DLX Exhaust System Conversion

[bvictory_imp]

I have seen several posts asking if the 2014 DLX four into two exhaust system can be installed on a 2013 CB1100 and the short answer is yes. It's not cheap! Even with picking up a set of used DLX headers and aftermarket slip-on mufflers, I spent right at $1,400 on this conversion.

Here is the Honda OEM parts you will need to purchase with prices from Pro Caliber. Note that the big dollar items are the left foot peg holder (left step holder) and left muffler cover. You can reuse the right muffler cover or not use muffler covers at all if you don't mind the black area behind the catalytic converters showing.

This picture of the standard and deluxe left step holder, shows that you need the deluxe version for the muffler mounting bracket molded in at the rear.

Removal of the original four into one exhaust is pretty straight forward. You have to remove the center stand and pick up DLX stand, plus fabricate a new spring mount if you want to retain this capability. I have the DLX center stand, but haven't come up with the spring mount yet, so it's still off for now.

Picture of both center stands:

Mounting the right engine header is easy since it uses the same mount locations and hardware that the original system used on that side. When mounting the left engine header, you will have to fabricate a mount just ahead of where the transmission shift lever comes out of the engine. I used the OEM hardware and rested the rubber bushing on the frame and everything feels solid. Don't forget to install new exhaust port gaskets, since the originals will be smashed from the first header.

I picked up a set of Over Racing slip-on mufflers from Samurider and they really look like good quality units. Installation was very easy, once you install the new bushing hardware on the new left step holder. I didn't like the gap left in between the muffler connections and the header catalytic converter side covers so I took the stock muffler covers and cut them down to fit this gap. Then I bolted them to hose clamps to attach them. I think it turned out pretty well, but had to cut a slot in the left cover which allows the kickstand to fully retract.

All in all, this project went very well and the new sound it great! Not to mention that I love the looks! Now I'm waiting for my fairing, side covers and engine guards to get her ready for riding season.

Here are pictures of the finished product:

That’s impressive work. I would love that setup but am not handy with metal fabrication and am scared of the $1,400 price tag just for parts.
