Default Thunderheader dyno chart
Could someone show me a dyno of the thunderheader dip. I just trying to see how big of a dip it is and is it noticable.
Thanks

Just put 2-1 Thunderheaders on my bone stock 11' Road Glide yesterday. Sending it off to get tuned today. I'll post up a chart in a week or two.

I dont see any dreaded areas of dipping. Not in my range of riding rpms at least. Below 2800 and after 5000???

Boy this exhaust REALLY opens up in the mid 3's and up.

The "dip" on my bike is between 2200 and 2800, but since the torque is already far higher at the bottom than a stock bike its not really that noticeable.

Sure, you have to downshift to pass quickly, but I didn't want a tractor that signs off at 4000rpm. My car is a diesel, that's boring enough...

Rich has been making the TH way before alot of these other copycat jump on the bandwangon companies started to catch on to "The newest Fad" . The TH is a very very good performing exhaust.
