RE: big city thundermonster baffels
They are just about as loud as drag pipes with no baffles. Thye provide backpressure and reversion wave reduction so that you get back low-end perfomance lost when going with straight pipes. I have them in my V&H Straight Shots, and I love the sound and perfomance. When I take it easy on the throttle, they're not obnoxious and I can ride through the neighbourhood without annoying my neighbours!
Cheers!

Hi all, I have a couple questions about these baffels. I have read alot of the threads on here about these and everyone seems to like them but no one has said whether it made their bike louder than the stock baffels that came in their pipes. That is my question. I have a set of hooker header trouble makers and i really like the sound but would like them to just be a bit louder. Does anyone have any input on how big of a difference or how little of a difference these baffels make. Also any one try the competition baffels that hooker makes for these pipes. Would they be louder? Does anyone know?

I am considering these baffles. I have '06 Heritage Classic with Stage 1 hi flow kit and V&H Big Shot Longs with their stock baffles. Do I do anything with the stock baffles or just install the Thundermonsters and go?

Hey fellas, I am looking into these as well. Does anyone know if I will need to retune my PCIII when I add them?

RE: big city thundermonster baffels
Don't want to highjack this thread, but I have a BCTM built for either a VH or SE Pro pipe collector. I used it to increase the performance of my TC88. I eliminated the stock baffle and adjusted the angle of the washer to increase torque. Sound got deeper and took alot of the shrill out of the megaphone style exhaust sound.
I'm higher compression, 95" and radically cammed with a new restrictor in the meg.
Will sell the BCTM for $25.00 shipped. Someone else might as well benefit from it.

did you guys install the thundermonsters in the same location as the stock baffles at the end of the pipe, or did you actually drill new holes and install them upstream further like is recommended...i'd rather not drill into my pipes if i don't have to.
