I have had a Thunderheader and a Drago Dragula 2-1 on my 2010 Street Glide. I would say the Drago is hands down better than TH in all categories.
Stainless steel header with ceramic coating made by Rush to Dragos specs, and the fit and finish is top notch, and the power gains are very impressive.

The only reason I got rid of my Drago 2-1 was because I wanted true duals and ended up with a 2-1-2 from fullsac. You cant go wrong with Drago and hes a great guy to deal with. Hes a gear head and all about performance and quality.

 

Why did you change from V&H?

 

Thanks for all the input. I was leaning toward Dragos, but wanted to see if there was anything over the top about thunderheader or negative about dragos.

 

Trying to convince myself that it's time to do the full system on my FLHX, the wife has V&H big radius pipes on her Fat Bob, sounds nice, but I want to go 2 into 1. I don't like the lopsided look of a single pipe under one side of the bagger, its an OCD thing I have with symmetry. So I am really leaning towards the Akrapovic open line right now.

 

I've got a like new Dragula 1 for sale if you are interested.

 

I have no experience with Drago, but from what I've seen of Rush products I would say it would be great quality.

 

I have no experience with Drago but I do have a thinderheader 2 into 1 on my bike now and love it. I have true dual thinderheader on my last two bikes. IMHO true dual thunderheaders are by far the best sounding exhaust on the market. Performance wise I got plenty of power from my thunderheaders as well.

 

You're not going to get a better tune than when Doc works on your bike!!!!

 

And of course.... you really can't answer the question of which exhaust is best, without addressing which cams to run and which oil to put in your motor.
