Road Star/Champion Exhaust Mod

[dbruce56]

After about 3 weeks of searching for ways to do this and overthinking it many times, I think I finally came up with the KISS solution. First picture shows the difference in length between the stock Yamaha pipes and the Cobra Slash tips that I have gotten. My initial thoughts were to use the Champion exhaust hanger (pic #2) with the bracket that came with the Cobras. This was a miserable failure. The inboard pipe hit the trailer hitch and both pipes hung entirely too low.
During a visit to my local Home Depot I came up with the idea to use angle iron as my homemade hanger. After a few mock ups I came up with the bracket shown in pic #3 and mounted in pic #4. Pictures 5 & 6 show the Cobras mounted to the bracket.
Next up: making extensions to make up for the difference in length between the 2 sets of pipes.

Gotta love the MacGyver in all of us. Good job, looking good. How do they sound? Do you need to adjust your map? Probably not if you didn't change air in.

I like to fab up my own stuff when possible. Most times it's less costly and the end result is so much more rewarding. Made the extensions last nite and did a final mount of the exhaust. Sounds great! Got exactly what I was hoping for in exhaust tone. And can still hear my radio. Should have pics of the final install and hopefully a video or sound bite up this evening.
Since I haven't change anything on the air intake side yet no need to rejet. At least for now,,,,

The extensions started with some 1 1/2"OD exhaust pipe. So maybe a 7 1/2' piece is overkill. Cut 2 sections, one 8" and the other 16". Add a 1 3/8"OD x 1 1/2"ID adapter. You'd think that the pipe would fit over the 1 3/8"OD trike extensions. Not. After a little work with a die grinder, a nice tight slip on fit. A couple of tacks hold the adapters to the pipe. Slid everthing together bolted the pipes to the bracket. Check for leaks,,,none.

Here's a video (crappy cell phone) of it running with Cobras and showing the other additions since I've had it.

Remembered this morning that I have a nice little camcorder at home. :gah: So, I may try to do a better video this evening. Also, forgot to add the Shark Audio 250w stereo.
