Thunder Monster Baffles!!!
Great to hear (what did you say?) you like them. I have the QQ series in both the Big Radius & the Double Barrels at 5.5-6" in. They both sound great. I started with the original BCT's 3 years ago on the BR pipes but switched to the QQ's in the spring of 08. The are almost as loud, have a deeper growl & less pop on decel in the BR's. I just put the QQ's in the Double Barrels & oh my! If you want them louder install them near the end of the pipe. Deeper sound & more torque 5-8" into the pipe. I finished installing mine at 11:30PM last week & rolled down the driveway at 11:31. 
Here's a pic of the DB's on the Heritage.

BCT QQ 1994's. I put them in 5.5" from the end of each pipe. I have to say the are louder in a good way, deeper sounding & just awesome now. And I can feel a little extra punch too!

OK, so I have V&H pipes on my fatboy. I bought the bike used so I don't know what the pipes are. They look like stepped drag pipes or straightshots, how do I tell and how do I get the baffles out? I can see a screw that is a few inches in from that end of the pipe. I hear you guys all talking about the heat shields and clamps? I don't see that? Also does anyone have these and if so how did they sound with the monster baffles. I like the sound with the stock V&H baffles but am looking for a little louder and a little meaner does that sound about right?
How do you put a picture in the post? Sorry I need some forum training wheels...
Thanks

QUESTION: Which of the 4 pipes above do you think will sound best with Thunder Monster baffles?

They will all sound great but anything over 100db will be very LOUD! I think my Big R's are 105+ & they rumble with the QQ's. The Double Barrels also sound great but not quite as loud as the BR's. Also there is a difference at idle between the TC88 & 96. I always thought the 96 sounded like crap at idle but the QQ's really helped out there. Still not as slow as the 88 but much better then before. If you want very LOUD, go with 105+ DB's. The 95-98 DB gange with the QQ's will rock at slower speeds but quiet down on the highway a bit. You still will know they are there for sure.
OK, I think I may have gotten the wrong size BCT for my Big Radius.
I took the V&H baffles out no problem, but the BCT is an extremely TIGHT FIT, so tight in fact, that I barely got them in half way and almost did not get them out. I had to spray the heck out of them with WD-40 and let them sit a while, and it still took two of us to get it out.
I am going to measure them to see what the size is.
Have any of you had these issues with this set up???
If these are the correct size, I will never get them in 6", and if I did, it would never need a screw to hold it in, as it would never come out!!!!
Thanks
