Default True Duals Info

I am new to the world of cycling and truly enjoy this forum. That being said, I have a question about the true duals. What are they? what is the difference between them and stock pipes?

Thanks in advance.

Dan

The difference is the duals do not have a crossover like the stock headpipes.

You will get balanced sound in comparison to the stock headpipes and mufflers.Most of the exhaust exits the right pipe on a stock set-up.That being said most will beg to differ but the stock headpipes will perform as well if not better than the dual set-up in most applications.A good 2 into 1 is better than all of them.

It's been discussed 10,000 times at the very least.

True Duals are dual exhaust, one for each cylinder and in the case of a bagger, one on each side. Stock pipes are essentially two into 1 into 2.

btw, please stop calling it cycling. That's what Lance Armstrong does.

Appearance and sound are matters of opinion but I happen to agree they look and sound better than stock.

Performance? Two bikes being equal no way.Yeah you get better performance because you change the air filter and add a tuning device at the same time you add the duals.Of course it is going to perform better than the stock configuration you are comparing it to.

Change the air filter,mufflers,and add a tuning device and the stock headpipes will perform just as well or better than the duals.

I notice on mine that it does kind of flatten out around 60, but the grunt in the beginning is a lot better than I had before.

Oliver is right about the performance. Most who install true duals forget that they have done something else to the bike at the same time. The increase in performance that they see usually comes from better breathing (a/c or mufflers) or from a good tuning job.

That said, I will soon put on some Bassani power curve true dual headers. If you are interested in duals + performance you may want to check into them.

The main thing ... do what you want ... it is your bike and you're riding her.

I had my 05 Road Glide dynotuned when I completed my stage 1.....screaming eagle air cleaner and HD touring slip-ons. I also had it dynotuned when I installed my Rinehart True-Duels. Where I did notice on the graph a little bit of a flat spot in the middle, I did pick up some horse power and a noticeable increase in grunt torque.
