- removing Screaming Eagle baffels & installing DKCustom Thunder torque Inserts. Took 2 1/2 hrs. Would've been easier if mufflers were off the bike & I had the proper tool. The bolts had a weird head I've never seen before but I just cut a slit in them & used a screw driver. The baffels weres stuck so I fired up the bike & blew them out. LOL whatever works!
Miss ole Robert. He was a really nice guy
I installed my TTI's into my new slip-ons with the baffles still in. The sound was already loud but not deep enough. After the installation, the volume was slightly less, the voice was definitely deeper and the low end torque was increased. I'm extremely happy with mine.
She's happy now. says she can hear me coming home :)
This thing really works.
For $18 a pair, I can make my own. Just two large washers and 1/4" bolt and you're in business. Takes about 1/2 hour to make and install. just experiment with washer size and adjust your air mixture screw and you're good to go!!
true but FI bikes don't have air mixture screws like carb'd bikes do & DK Customs TTI's have a dished shape that helps with the air flow. You could also bend your washer the same way but the TTI's have been tested & design special & I think would still work a little better than the old washer or lolipop methods. Only dyno test on same bike using different methods would prove which is best Thanks
yeah I'm glad about the pipes you almost caught us. haha
Thank You. I turning them 180 inside mufflers to see what difference it makes as a test
Looks like a fancy set of lollipops
Yes, that's basically what they are
I think that's their nickname. 🍭🏍
Sounds great. If your wife can't hear that I would say a trip to the ear doctor is in order.
Sounds very nice good job!
Dude, that would have taken 15 seconds to fire up the the screaming eagles before removing the baffles for comparison purposes. I believe they look just to be alittle too large for the pipe..You didnt even comment about the sound changes.
Thanks for the info!
thats a tamper proof torx bit for anyone else that comes across it
I have vance and hines 2" slip-ons and i"m curious do you need to take the baffles out to install these thunder torque inserts?
No you can leave in the baffles but then you'd need to get different size TTI's than what I used contact DK Customs they can tell you exactly what to order. I removed my baffles because I wanted them louder!
Don't worry lol my wife decided to bang my pipes against concrete to remove the baffle on one pipe .. she ended up flattening the pipe .. so I had to cut off two inches .. and then the baffle came right out
ROFL
Which Thunder Torque inserts did you get? W118, 158, or 258? I have a 2011 Forty Eight with the same (except in black) Screaming Eagle exhaust...
I got the 258 W because I removed the stock baffles in the SE slip ons to be LOUD! If you're keeping the baffles in to stay quite you'd get a different model TTI. An email to DK Customs will get you a fast response as to which one will work best for your setup. I installed them in the same hole that was used for the baffles bolt, just drilled it out larger. I faced them so the cone faces inward for best mid range torque. Good luck & enjoy them when you get them.
P.S. If you remove the baffles the stock bolt has a special head I didn't have the proper tool to remove. I cut a slit across the bolt head and used a screw driver to remove it.
Have you turned them at all to open it up a little more?
WarrPigg1969 Yes I tried them with the cone facing outward which gave me more top end on the highway but killed the lower end torque off the line so I turned them back facing inward for best overall performance
Thanks... got mine today, gonna try to get them in on Sunday.... don't do too much highway riding, so I'll probably set mine up like yours.... and just so I get it right, with you saying you have them facing inward, that means when you look in the pipe you see the back of the plate where the bolt is welded on, right?
WarrPigg1969 correct.
Finally getting around to installing mine.... got the 2 torx bolts out, but couldn't pull the baffles out... no garage, so the bike sits out, covered up when it rains... so there's some rust in there... any suggestions? Sorry for bein a nube!!! LOL
Mine were fairly new & I still had trouble getting them out one came out easy. The other took hours of WD 40, pulling with vice grips, made up two hooks from wire coat hangers & tried pulling out. After getting it to loosen a little but not enough to come out I started bike and rev'd it until it blew out the back. Good luck hope it comes out OK & don't be sorry I learn something new everyday
Slide hammer.
Hello. Did you have to do a re-tune or recalibration?
Nope I run the Cobra FI 2000 R fuel unit it automatically adjust to any changes you make on the bike. I've changed the air cleaner style 3 times and pipes 4 times with out having to do anything else
How are them torque cones
so you put the baffles back in after the TTI'S?
no I left the baffles out
Im sure Jodie will it to. Lol
Hello Robert. . would it be possible to remove the baffles from only one pipe and leave the other as is to get moderate sound level. .?
+bob6168able I don't think that would work. It'd make the bike run uneven, ( different back pressure for each cylinder ). Even with the factory cross over pipe I doubt it would run balanced. You can try removing and cutting the baffles shorter, ( equal lengths ) then replacing them, to get more sound without going too loud or loosing the needed back pressure for low end torque on the FI bikes. If you've got a carb'd bike you'd probably need to re-jet the carb. If this is the only thing you change on an FI bike you shouldn't need to re-flash the computer or install a fuel processor until you change your air cleaner also. The factory computer should be able to adjust for shortening the baffles just a bit.
how did you install these?
I removed the baffles by first cutting a slot for a screw driver in the bolts holding in the baffles because it had a very strange bolt head style I didn't have a tool for. After removing the baffles i drilled out the hole for that bolt in the muffler a little bigger so the TTI's would fit through. I pointed the TTI's with the cone shape facing forward as my test rides showed that gave me the best torque through out the throttle range. I hope this answers your question well enough
thanks for the very detailed answer! im just wondering though, how did the TTI slide into the exhaust with the circular head and the bolt on it?
the threaded bolt part of the TTI is welded to the back of the circular part. You just slide it into the opened end of the muffler at a slightly horizontal angle and drop the threaded end into the hole you over drilled that the baffles originally used and the TTI flips straight up into place Then tighten the nut & lock washer on the bottom of the bolt using some blue lock tite and a stick to keep the TTi from turning inside the mufler while you tighten the nut underneath
Robert Robb cool thank you
