Does anyone have any experience with these, either running them or tuning with them?

I love my Factcat, but the loudness is getting to me on 12-14 hour days, even with earplugs.

 

I looked at these last fall, but the $1000 price tag scared me away.

I would like to find a good performing EPA approved exhaust, and this looked to fit the bill. But I didn't really hear from anyone who was using them.

Yeah, it's a lot of money to put into a system that there isn't much feedback on. I've heard a YouTube clip of the Stealth mufflers, and they seem quieter, but poorly-recorded youtube videos played back over laptop speakers aren't the best guide.

I'm not so worried about the EPA stamp (though that is one less thing to be hassled about), I'm just tired of being half-deaf after a long day in the saddle.

 

I modded my fatcat quiet baffle in search of some more quiet. Pretty simple and effective. Toned it down some but more importantly seemed to make a lot more of the sound seem to come out the actual tailpipe behind me and not reverb in the pipe and come up towards the rider. The quiet baffle from the inside out is a louvered core, air gap steel cyclinder full of holes, steel wool, fiberglass packing (very thin amount) and tape.

The mod that I did was to remove the baffle, cut the fiberglass and steel wool with one slice from front to back (set them aside for later use), cut off the steel cylinder with holes, reapply the steel wool directly on the louvered core followed by the fiberglass packing (letting both layers overlap due to the new smaller diameter), wrap the baffle with a couple pieces of masking tape to hold it in place, wrap the baffle in wire steel wire (wire hanger should work), and then slip the baffle back in place. Took a few miles for it to "burn in" and the smell to go away. The outcome was subtle but noticable and most noticable at cruising speeds. Free mod which is a lot better than $1,000.00

I have not run the TDX but have run the Stealth mufflers for two years and will say they are great for sound and distance. I have ordered a V&H power dual and 54H cam and will install with the stealth mufflers on my 2011 Road Glide 103 with PC-V and auto tune.

 

I googled and came up with these results:

I have experience with dropping the Fat Cat and moving over to the Bub7 TD's, but not the Stealth's. It was a blessing to my ears and I actually gained numbers on both ends.

 

Yeah, I saw that thread, but that was specifically about the mufflers only, not the entire TDX system. Since my bike's a 2010, I'm not going back to the stock headpipe with the catalytic converter in it. The Bub headpipe is stepped, which should help dramatically over the stock-style headpipe.

And I'm assuming the TDX system will work better than the true duals.

 

I wonder if the right side is still the dominate pipe and if the crossover is a 2-1-2?

 

Adam,

My plan is to modify my baffle as well, but I can't get the damn thing out of the muffler.

I want to remove the packing, cut a door into the perforated outer can, fill gap with packing, weld the door back into the outer can, rewrap the packing, and put it back in the muffler.

That should quiet it down a lot, and make it deeper at the same time. Now I just need to figure out how to get the baffle out of the muffler......tried everything I could last year and only got it to move about 15".

I replaced the exhaust on my 2009 Ultra Classic with the Bub 7 True Dual Stealth TDX system and love it. I wanted something that wouldn't give me a headache when cruising but would still give me performance. I first installed the Bub 7 True Dual Stealth (non-TDX) but my wife didn't like the way the pipe exited the left side of the bike. She worried that it was too close to her leg and would be too hot. Notwithstanding her concerns, the bike performed great and was about as loud as stock at cruising speed. If you got on it though, it had a nice growl.

However, I gave into my wife's wishes and swapped out the Stealth for the Stealth TDX. I spoke with the engineer at Bub about the TDX and he said that the TDX with the crossover was the best performing pipe they make. I have a TTS Mastertune on the bike and had it dyno'd with the Stealth and again with the Stealth TDX. Changing to the Stealth TDX from the Stealth non-TDX, I gained 7hp.

I've ridden with the Stealth TDX full system for 500 miles and the bike runs flawlessly and sounds just the way I wanted. Great Harley growl when you roll on it hard but quiet as stock at cruising speed. In fact, friends riding behind me on their Ultra's said they can't hear my exhaust at cruising speed or when I ease in the throttle to pass someone. I can ride all day without the resulting headache or buzzing in my ears. I also enjoy the stereo much more because I don't have to turn it up so high to hear it over the exhaust anymore.

My friends who all have Reinhart True Duals on their Ultra Classics, have said they prefer the way the TDX rear pipe is routed on the right side of the engine. They say it looks better, allows easier access to various engine components, and is routed away from the passenger's right leg making it cooler.
