Default 08 Sportster True Dual Exhaust Bagger Style Video Added.

Well, after a long while of putting this off I jumped in head first. Mind you this is my first attempt at exhaust building. I used the stock head pipes from my 08 sportster. I bought a biltwell weldup kit a while back and broke it out of the attic. The front pipe passes under the belt between the tire and master cylinder (plenty of room). The rear pipe runs straight down and back. Yes I know the left pipe is higher than the right one (work in progress). I am running the wetdreamz map right now (it is a similar exhaust system (basically drag pipes) but I will do a ride test in a few) but as of now that is what is loaded. Used 50' of that black exhaust wrap. Here are the pictures. Video of it idling being uploaded as I type, will post when I get it. The smoke is from burning in the wrap.

Not a bad look if you can raise the right side and maybe tuck them in closer to the bike a little more. Good job.

Cool "Enter the Dragon" poster!

Well, it runs pretty well. Tuning is pretty close, no pinging and plenty of low end. The exhaust is a lot quieter compared to the thunder head (from where I am sitting). The exhaust is noticable hotter than my thunderheader. That is the difference between the ceramic coating and not. Later on I am going to get some rigid mount slipons without the crossover provisions. WOT is pretty loud but cruseing is not as loud as you would think. I am going to get some 1/2 (probaby) round bar stock and make a U shaped brace to weld under the pipes around the tire so the pipe is not only supported by the weld and the wrap (ya right on the wrap).

Here is the video.

Added some 3/16" x 1" flat stock around the inner perimeter of the pipes like a U shape to keep the left pipe from being totally supported by the welds. Ill get a video of me riding later today or tomorrow. I like the fact it is quiet until I dont want it to be. Upon cold start I get the sputters and misses but that is above my head with the power commander. I tried adding and subtracting fuel in the range but did not help. Leaving the low range tuning to the pros. Not bad for about 8 hours and <$200. Tweeked the bracket to lower the left pipe to pretty close to the right one.

Wow! Nice. I wonder if a welded in crossover might help with the tuning.

I like the look from the back, but shouldn't the pipes be the same length or close to the same?

In theory yes, but either way on this bike you will have a long pipe and a short one, even if the front went straight back and the rear curved under to the other side. Even the BT true dual kits the pipes are uneven length. The rear cylinder on the left side and the front cylinder running the length of the bike on the right side. If I had the room I would have did a 180 with the rear pipe and came out the left side in front of the battery cover but that hinders passenger foot room since our bikes are so short. A crossover might help the tuning, but once it is warm it runs fine (as the previous exhaust did). Idle is 950 to 1000 when warm. Thinking of some randy redneck echo tips with cone muffler inserts if the noise becomes a problem with johnny law.
