Pro Pipe vs. Thunderheader for FB
Hey Guys.
I'm a Dyna rider today, but looks like I might be making the switch to a 2010 Fatboy. Right now it has stock exhaust and as I negotiate with the dealer, I am asking for either a Pro Pipe or Thunderheader.
As I am a bit short on time today, I was hoping you guys could offer some opinions on which way to go. Or if I should go with something different.
Thanks!

any 2 - 2 pipe with a crossover is going to give good performance. there isn't enough difference to really make an argument. at that point it is all about looks for the most part.
now a true dual without a crossover pipe is likely to give less low end torque.

Thunderheader. Will give good low end torque and sounds great. My 09 Night Train has a thunderheader on it and with that and the 204 cams and the Thundermax Fuel control I am getting 85hp and 104 ftlbs of torque.
A 2-1 is the pipe to have to make low end power. If the cross over was that great no one would change out their stock pipes. It's a proven fact you lose low end torque by going to a 2-2 exhaust.
I prefer the Thunderheader (have one on both my bikes) but they have gotten good numbers off the Pro Pipe also. Most peoples objection to the Thunderheader is it's ugly.

I ran a TH for 20k miles. I can tell zero difference with the stock headers on my SB with a crossover running Cycle Shack 1.75" baffles.
Actually my TH did not really make a difference until around 3000 RPM. On the Dyno there is a noticeable dip from the TH when rolling on, and then it comes on around 3000 RPM like I said.
Nevertheless everyone has there own opinion. Even me. SO take it all with a grain of salt.

Between the two I like the looks of the V&H's better. Performance wise the TH may make a tiny bit better #'s..? depends on who does the tuning.
Both are loud but not obnoxious.
Either one will do a good job. So it more personal taste.

I just put a Thunderheader on the Dyna which previously had a V&H propipe. I much prefer the Thunderheader to the propipe. The fatcat is a great pipe too but it does sit very low so if you are concerned about the bottom of it scraping you might want to consider the lowcat as it sits higher and should not have that issue. My Thunderheader is black and has been on for about 50 miles and the head pipes are already starting to turn colors. It could be my tune but it looks like it will be jet hot coated when the time comes.
