I have V&H Straightshots on my 2002 XL1200C. I was told by a HD mechanic that if you cut the front 4 fins off of the baffle you will gain about 5 horsepower. As a bonus the pipes are louder!! Just don't cut the back of the baffle since that is were it gets fastened to the pipe. I did it and you can notice the difference.

 

I have put on my 1200C (Short staggered) by Vance and Hines and I love it. I’m positive that (Straight Shots) are the same or better.
You can go to their website and see and hear the sound.

Vance and Hines sound great on my 883, I went with the slip-ons.

 

I went with the vance/hines straight shot slip ons.
They have a great sound.

 

I have them on my 2000 1200C. They were loud enough to sound excellent, but not enough to bother the local police force (yet!)
I pulled the V/H baffles and re[laced them with Thunder Monster Performance Baffles...Thought they sounded nice before but they're even better now!
