Made a big difference in sound when I used the Thunder Monster baffles on a Yamaha (about 5 or 6 years ago) to make it sound like a Harley! (It never sounded like one, by the way, but sounded alot better.) I bet they'll sound pretty good on a Harley. They used to have a guy there who answered the phone when I called, who was really a big help. (Jim, I think?) Just tell him what you want, and he'll know if something will fit.

Strong throaty sound without the obnoxious volume
I've heard a number of positive comments on Big City Thunder baffles. Supposedly reduces the loudness factor from a 9 to 7 vs unbaffled straight pipes. The install is easy.
I have a set of brand new BCTB's still in the box unopened for sale. Can save you $50 bucks! Wound up buying baffled TAB slipons for $275 that have a similar effect. PM me if you have any interest.

I tried them out in my Deuce with the Mean Mothers. I may be in the minority but I didn't like them. The Mean Mothers sounded way to tinny and I could tell a drop in performance. For me the standard baffle was plenty loud in them although it was basically a straight through glass pack. To each his own, but I wouldn't bother.

I installed some a couple weeks ago in my V&H Big Shots and don't really notice a sound difference. On a positive note, and it might just be my mind playing tricks on me, I noticed a bit more low end throttle response...

I ran them in Vance and Hines Straightshots when I had my Sporty. I tried SE slip ons, drag pipes, VH Straightshots with baffles, and the Straightshots with Thunder Monsters. The latter is what I liked the best. Decently deep rumbly, thumpy sound and the bike ran purty darn good too.

I thought a quieter sound was the primary purpose of baffles.....
. I wouldn't expect much improvement in performance, if any at all (assuming tuned up).IMO straight pipes are a bit too much for my neighborhood.
