Project FXDXT is underway
should have em ordered by next friday maybe sooner
The fatcat install was fine with the exception of the muffler in relation to my axle which is turned around backwards for easy removal. The nut and end of the axle were close enough to hit the muffler with the hardware that came with the pipe. D&D is a TRUE FIT pipe meaning it fits very tight. Not a problem but it took a few spacers and washers to get this right.
Initially I used 5 lock washers between the bracket and the muffler to space it out which still elft it very close until I sat on the bike at which point the muffler drops well below the axle. I went through my collection of random hardware and found some Harley Goodies floorboard extensions for baggers which are black and fit the bill nicely. I managed to get the spacer in the rear position on the bracket but could not get the front one in no matter how hard I tugged as it was just a tad bit too long. So, I used a stack of lock washers again, I don't recall how many but quite a few and there is now plenty of clearance between the muffler and the axle.
Now on the the performance and sound of the pipe. This is the quiet baffle D&D fatcat in black. The fit and finish on the pipe is excellent as is to be expected from D&D. the entire pipe is black and it comes with the heat shields and all needed hardware with the exception of the afore mentioned spacers. I also needed longer bolts for the spacers which I had laying around.
The flanges on fatcats are welded on so there is no need to swap them from your old pipe with the circlips which ensures that there wil be no scratches on the pipe. The bracket for the front lower mount by the cam cover is not set up like the TH where there is pretty much no way to get it on without scratching the finish on the pipe as well. I liek how this is all thought out on this pipe. The easiest way to get the headers on and tightened down is to use a wobbly extension with a short 1/2" socket. The upper rear flange nut it a real pain to get to due to the bend in the pipe. The rear heat shield had to be taken (as is normal with D&D) off and there was still barely room to get the socket on the nut due to the bend in the pipe. Take the shield off BEFORE you mount the headers as one of the clamps was mounted as such that the battery box was kind of in the way to get it off although we managed to get it off.
The mounting bracket (which is always a concern of mine since the TH seems very sturdy and has shown no signs of cracking yet (although it has only been a few days) so I am hoping that it works out like the V&H bracket that never had an issue.
The mounting bracket also utilizes the same holes on the tranny as the V&H bracket (and one more hole that the V&H bracket did not use) so it certainly mounts differently than the TH bracket as that utilized the hole right behind the clutch cable.
Once everything was bolted up (I used new SE gaskets) I started it up. My very first thought was that the pipe was very quiet (at least to my ears). The V&H I was running had some different baffle that was welded in and it was quite loud. The Thunderheader was louder as well. Not to say this pipe is quiet as it is no where near quiet, but it has a different tone altogether. The TH was a bit deeper and louder. This si quite deep and the pipe needs to break in as the pack ing will wear as time goes on and the sound will get deeper and a bit louder.
Now for the acid test. How does it perform? The fatcat packs a nice punch. I wish I had access to a Dyno as I would be able to more accurately state my results but unfortunately as of right now I do now without shelling out tons of money. Anyway, it seems to pack a really nice amount of low end grunt. I could call this bike the stump puller now. I am not sure if this fatcat or the TH has more low end really. The top end is great as well. I avhe only ridden about 300 miles since I put the pipe on ( a short ride home, around town Saturday and a solo Dyna Mobbin run on Sunday in the Canyon's) but I am digging this pipe. kI managed to elan the bike over enough to eat up a bit of DK customs stealth beartraps and the pipe seemed to be nowhere near the ground.
I am more than happy with this performance and the looks of the pipe are great too. I'll snap a few pics when I get a chance and post them.
I also got my VROD bags on the bike and will see what you guys think. I used easy brackets to mount them and with my qd sissy bar mounting pints on the bike and then the easy brackets mounting points the bags are out kind of far from the struts, but what can I do, I want it all. I noticed this morning the the right easy bracket is wobbling as bit so I am going to tighten down the nut for the locking latch and see if that helps. I did the same on the other side and it is rock solid.
In summary, if you are thinking about a fatcat for your Dyna I would recommend it although I have not put enough miles on the bike to see if there are any bugs or other issues aside from the muffler proximity to the axle that will need to be worked out. Stay tuned for more info.
