I have a 2002 FXD with stage 1 AC and V&H Straightshots. I bought the bike used in December w/ these modifications already installed. I am pretty sure the Straightshots don't have any baffles (pic below), and the sound is just TOO LOUD! I like loud, but this is just annoying!!

I have done a little searching here and at another website and have come to the conclusion that I want the Big City Thunder baffles. Before I go forward w/ the purchase, I thought I would solicit feedback from you fine folks.

Anyone here used the Big City Thunder baffles? Any other aftermarket options I should check in to? I want a nice, reasonably loud, rumble once this is done!

Thanks in advance for any feedback!!:cheers:

I prefer the HP Plus baffles. I think that they sound better and they definitely make better power on the dyno. Oh yeah, and they are half the price.....Bill

What pipes did you run them in? What was the
difference in the dyno results between the
Thunder Monsters and HP Plus baffles? At what rpm?

I have the ThunderMonsters installed in V&H Big Shot Staggereds on an '04 FXSTI. I really like them but don't count on them to be quiet. They may be a little quieter than just straight pipes but probably not by much. They run good though and I like'em. ~!Awesome!

I ordered 3 different sizes of the "thunder products" baffles to use in testing. I have tried them in a variety of pipes from short drag style to long dual style. The HP Plus baffles have always produced substantially more low RPM torque and better HP. I do not always use the HP plus baffles full length.I have them cut down to different lenghts. I only use enough baffle to get all of the low end torque possible without losing HP. If I have a pipe with a curved end that will not allow me to slide a baffle in then I use the washer lollipop trick and set the angle for best torque/HP. Not the best sounding but works well......Bill

I just thought I should post an update:

After all the research, I ended up buying the replacement V&H baffles for my Straightshots. I got the rid of the obnoxious popping on deceleration and upshifting. The sound is still louder than stock, but not too much. Just what a Harley should sound like....in my opinion!!

Thanks again for the replies!!!!:cheers:
