I want to remove the baffles on my 2014 ultra classic for better sound.What to know if it will cause any other problems with the exhaust system or affect my warranty in any way

 

Stock systems with baffles removed sound louder, but whether it sounds better is debatable. Most times, it seems to result in annoying popping/crackling whenever decelerating. Over the years, I've learned that you get much better results with properly designed exhaust systems; either slip-ons, or a full system. And now that it's so cheap and easy to buy/use a tuner, there's no reason to go without a re-tune. Your bike will run so much better, regardless of what exhaust you run.

 

Welcome to the forum!

Removing the baffles will result in a significant loss of low and mid range power, drop in mpg, and while louder, the likelihood is that you won't like the sloppy blubbery sound.

We just did the above a couple of weeks ago with 2 different 2014 Touring models...a Street Glide and a Tri-Glide.

Then we put some W258 Thunder Torque Inserts in them (after removing the baffles) and were VERY Surprised at how good they sounded, on top of that, they produced as much, or more, power as top performance exhaust systems...that was a big surprise too.

We should have a video of the sound shortly.

 

Pick up a set of Cycle Shack slip-ons, they can be had for around $300 and will look, sound and perform way better than stock mufflers with the baffles drilled out. And as mentioned above, get a tuner of some sort, even a stock bike will perform significantly better with a proper tune.

 

Plus one on the DK Customs TTI's. I am running them on my 2014 SGS with Rush Big Louie's with no baffles, K&N Filter in stock back plate and cover and a FP3. Love the sound and the performance.

 

I would like my pipes to be a little louder and I'm always looking for more performance. I am considering getting this TTI setup for my V&H 4" slash rounds and FP3. This is what DK sent me in an email:

"If you leave the baffles in, you will want to use the W158 ThunderTorque Inserts. It will not make it louder. It will deepen the tonea bit. It will increase the low and mid range power. You will notneed to re-tune, although an auto-tune with your FP3 may yield a bit of anincrease in power and mpg.

If you remove the baffles, then you will want to use the W258Thunder Torque Inserts. It will be louder. It will have more powerthrough out the entire RPM range, even with no auto-tune (and a slight increasein MPG). Then if you do an auto-tune there will be yet another increasein power & MPG.

The TTI's work very well with the V&H slip-ons at increasing performance.

Does anyone have this TTI system with V&H slipons? How do they work? Better Performance? How much louder with these vs. leaving my baffles in? Are you happy with them?

 

You can do a search on this forum for TTI or Thunder Torque Inserts, hundreds of folks have posted their experience and thoughts on using them.

You can also go to youtube and do a search for DK Thunder Torque and see and hear a lot of videos.

Here are a couple that we have done-





Here is a dyno chart with the low side of what to expect in power increase-

 

Thanks Kevin!

 

Don't do it! I just bought a 13 Street Glide with V&H pipes and the baffles removed. It sounds horrible! Like a Jake brake every time I pull in the clutch to change gears or let off of the throttle. Yes, I knew it going into it but it's cheaper to replace baffles than it is to buy slip ons.

 

Here's the video I mentioned previously.

Not only is it a good sound (to my ears), but it produces excellent power!
