Want the cat removed...go to www.fullsac.com and read what they have to say. Call Steve and talk to him--very heplfull and knowledgeable. He can remove the cat and send your pipe back to you in a few days. Stock look and no cat!!
Well I thought about that but if our state ever decides they're going to test bikes (I live on the "left" coast) I'd like to have the take-offs to put back on again.
On the dyno I lost 4 ft lbs of torque when I went to true duals on the '08, I can't tell when riding it. However, not once this summer did it get too hot to ride, it made a huge difference! Last year I had to shut the motor off a couple of time.

Been running V&H True Duals and can't really notice a ny type of loss. They do sound awesome and as somebody else noted, it's a bagger, not a drag bike.

I look at the 2:1 systems differently.
Yes, I run them.
Reason?
I asked myself a question when I was building my SG motor.
"Why am I building a motor for power when I reduce the power using a true dual?"
I couldn't find a reasonable answer so I went with the Bassani Road Rage 2:1 system.
I know the true duals look better, more balanced...but if you are now, or will ever, "hot rod" your motor...I say save the money and buy a pipe once, go with the 2:1 system.

Your bike will be louder especially since you are changing the cams too. When I went from my stock headers with Samson slipons to V&H dresser duals and added the cams, my bike became too loud. It was much louder. It was so loud I had to change out the slipons. Some say the Monster Ovals are not loud enough, but with dual headers and cams, they sound great! Plus with a little more back pressure from the MOs gives back some torque.

I reckon the true duals v 2 into 1 difference is an internet myth. It is quite likely that if we take the same bike and dyno it to dial it in to each system there will be a difference between the two setups, but I doubt if it will be enough to argue over.
I have an S&S 107 and before installing it asked S&S what systems they recommended for it and true duals was one of their options. On the dyno I get slightly better figures than they give in their catalogue and a similar shape torque curve. I am very happy!
Go with which ever system you fancy most. True duals will be great. Just don't expect it to behave as popular myth says it will!

Reason: Grammar
Like other have already said, the difference is little. I had true duals before and after my build. After the dyno with TD, my no's. were 92hp and 108tq. After I put on the 2 to 1 TH I gained 2 hp and 2 lb's tq and a lot of noise.The TD I had were V&H with Wild Piggs, and the sound was kinds tinnie, but load. The TH are just load, but in a deeper way. I will have to admit the heat was not as bad with the TD as it is with TH.
