Big City Thunder says to install their baffles 12"-16" from the end of the tail pipe (in the last straight section of pipe), for maximum benefit. The closer to the end of the pipe you go, the more low end torque you lose.


I love the Thunder Monster Baffle in my Pro Pipe. It sounds like an open pipe at full throttle, has a deep tone, and is somewhat quiet at idle. The low end torque is awesome!

You will also notice that the jake bake sound on decel and between shifts will be greatly reduced if not gone. You can place them anywhere in the pipes you want, but looking at your picture, I'd put them as deep as you can in your tips. Most baffle manufacturers recommend installing them around 6 inches into the pipe.
The difference between the Thunder Monster baffles and the "lollipop" washer is that the complete baffle actually makes the pipe a bit smaller and will actually give you a bit more back-pressure than just the washer which is a good thing. Also the diameter of the "lollipop" and the hole are precise in the Thunder Monsters due to the research and development that went into the product. That's not saying these won't work, because they should and the results should be noticeable.

Well, I couldn't put them in this week, so next weekend's the new time to install them. If it is true about putting them farther in to increase low-end, I think I'll go deeper than what I was originally going to do.



I may also weld up new ones with a bigger washer on the ends...

That is what Big City Thunder told me on the phone. It works great in my bike. If you're going to weld up new ones, why don't you get two 4" long pieces of s/s pipe that fit the insides of your pipes, and weld a stem (1/4" rod) and a small washer to them, at one end of the pipe, so that the washer is centered in the opening. Drill a 1/4" hole about 1" in from the other end, and thread it, or weld a nut to the inside of the pipe. Presto!! You've got Thunder Monster Baffles!! Now drill a 1/4" hole through your pipes, and slide the baffle in, and bolt it in place with a button head allen bolt.


I wouldn't make the washers bigger than what you have shown. The whole point is to create some turbulance, not to block off the exhaust.

Rode all day. Deeper tone, less high tone, no more jake on decel. Not too sure about the torque, I am in need of a map to appreciate that I think.

Been looking at baffle alternatives and ran across this thread and I'm looking for anyone's input that has done this. Here's an article that I found. HERE I think I might try it, maybe with a slight mod to it. Not really overly concerned about squeezing every little ounce of performance outta my bike. Thoughts?

So there you go Mark!
Interesting options....man you can try both. The washer baffle is cheap enough if you don't like it, then you can go with the other option....the monster baffles look like they would be a "shorter" solution then the V&H quiet baffles, which appear to be too long for what you are trying to accomplish.

wanted to share this utube link as it applies to the "butterfly" baffle solution being discussed here. The link provides some "real time" testing so you can hear the sound diffs. just thought this might help;
