They will quiet your straight pipes and make them lower and deeper sounding, not so "tinny or metallic" sounding and will give you more back pressure, hence more low-end.
You will need to pull your pipes off and drill a hole on the rear on the back side of your pipes and then insert the baffle, and button head screw it down.
Use the heat resistant Loctite.

I gave my brother a set of those pipes with some BCT baffles in them. I don't believe he is using them so the baffles may be for sale. I can get ahold of him and ask if you'd like.
You can PM me.

After calling & talking to the guy at BCT (can't remember his name) I went with the BCT QQ baffles. Got improved low end torque & a awesome deep exhaust sound. Call him up he will tell you what you need to do what you are wanting.

The directions will advise, but you need to set the baffles in the pipe deeper than the stock baffle mounting hole. If I remember right it was a minimum of 6".

I wouldn't spend the money on the QQ's. I actually felt a loss of power with the QQ's. The bike just wouldn't accelerate very sluggish. They also sound like a metric with a weird poppy sound. Sounds like half harley and half ***** wonka bubble machine. Then when you get hard on the throttle it sounds raspy and nasty. A couple guys at work that were behind me commented on my bike asking the hell did I do, "your bike sounds like ***". They liked it before, so that evening I cut the baffles.
With the QQ's installed. They sound a lot worse in person!!
I cut the cones off of the QQ's to make them like the standard monster baffles. It has a decel sound kind of like fishtails would make let off the throttle. I've read that cutting the stock baffle and bolting it behind the BCT will make that go away. Its raining so I didn't get it out on the road for a test run. I'll do it tomorrow. I should have backed up past the wall, theres a little echo.
Cut to be like the Monster baffles. And these sound a lot better in person.
