what is a a better exhaust 2 into 1 or true dual thunderheaders ,,is there any difference in power , I have thunder header slip ons on now , ..also the crossover pipe does this effect torque , or is it better wit 2 into 1 thanks

 

its mostly personal preference. duals are more expensive but sound better IMHO. supposedly 2 into 1 makes more power on the dyno but i don't think the average person could tell on properly tuned bikes. I've ran true dual Thunderheaders on my last two bikes and both flat hauled ***. my most recent would fry the tire roll on in first gear with my skinny buddy riding it. so don't listen to everyone that says duals are crap and don't make power. get what makes you happy. Here are both bikes so i don't get called a liar.

 

Pick what makes you happy looks and sound wise. I love the look and sound of a thunderheader. But I also have a soft spot for Rinehart true duals.
