Put in baffles in my V&H Big shots, also added a Screamin Eagle heavy breather.

Dyno results   96 HP, up from 88. Torque 114, up from 106.

Can notice the difference, happy with the results.

Nice improvement. Are there any other mods besides the pipe, heavy breather and tune?

Nice. I just fitted v&h quiet baffles to my big shots which improved torque but lost hp. Which baffles are you using?

FB, nope baffles and SE heavy breather.
D, fck unsure, V&H baffles for big shots.

What tuner system are you using ? And what baffles did you use in the end ?

My 2008 CVO Springer I can use the "original up to 2008 SERT" or the TTS system

My bike runs well , never been near a Dyno , not my style. V&H Big Shot Staggered and the stock US market Heavy Breather

It's probably the fastest "off the line" Harley I've ridden ( and I've ridden many many bikes !)

A good mate had a 2011 103 cube with a stage 4 kit , and my Springer would SPANK it no worries.

3 of my riding crew have 2002/3 V Rods and they have to work the fuckers to get past me
