Did you mount 4-6" in from the end of the pipes like the installation instructions suggest, or did you use the original holes? Short shots may be a little different than my longshots though.

Trying to figure out what I'll do when I get around to installing mine. Not too keen on the idea of drilling a hole in my exhaust.

 

You guys filling the old hole that held the original baffles or just putting a bolt in there??

 

After you remove the heat shields, measure 6in from the back of the pipe.That is where you drill the new hole. I talked to Thunder monster company and they said, to get the full effect of the baffels it must be at least 6inches up in the pipes, that is where the sweet spot is.It is not necessary to fill or plug the stock baffel hole.Just make sure that the little washer thing inside the baffel is facing to the rear of the exhaust.

Hmm.... Sounds like a mod I may be interested in. How's the low end power loss in a real world scenario? I'm just runnin' a stock TC88 and need all the low end I can get...

 

There is no low end loss. You actually gain a little bit because these baffles have the washer mounted in the baffle that actually increases back pressure, therefore increasing torque.

 

I went 5" in. They must be at least 3". 6" is ideal but my heat shield clamp was right at 6" on one of the pipes. They feel and sound good at 5". Drilling a hole in the pipe is nothing. Just start with a small bit to get a small hole in. Then up to a 1/4" bit and grind it open a little larger than 1/4" and the bolt for the baffles will go right in. Easy as pie!!!!

 

Here is just one link I found where there is some different opinions on how they performed

there are a few more links

As for drilling the hole, Use a center punch to start the drilling. Start with some smaller drill bit sizes and work your way up. Also make sure to drill the holes underneath the heatshields so that they are not visible when putting them back on the bike. And the last thing you need to know is to face the lollipop/sight towards the exit of the pipe. Im **** about things so I made sure both of mine were in the same position.

There is no need to cover the original hole as it is not going to affect anything.

 

I have an '07 FLSTC with Rush Slip-ons. I had pulled the baffles and ran it straight for a little while until my Thunder Monster Baffles came in. I ran my bike with these baffles for about six months. I just took them back out and replaced the Rush baffles.

With the Thunder Monster Baffles there was a small increase in low end power from the straight pipes. The sound was cleaner than straight pipes After I replaced the Rush baffles I found the tone to be more to my liking and the power was noticably better w/ Rush baffles. Still not happy with my set-up. In search for the perfect combination of loud pipes with a good tone. I don't think I'll use these baffles in the future. It's a lot of money for a washer and wasn't too impressed with the results.

 

Hey cryan9, next time I ride to Pasadena I'll bring you my shirt. I can cut the sleeves off if you'd like. Now you can have 3 shirts.
