The twins have worked awsome for me. The amount of tuning is the same as for the singel pipe. But the twins has a way better trottle respons, and they make the sled really strong. I`ll never go back to singel again on this sled, that`s for sure.
I use Powercommander 5 for tuning. You should be aware of this, if you plan to tune the sled on the hills, you won`t get the full potentional out of it.
I did tune the top end in a dyno, and I was suprised how much the difference in the map, affected the HP.
F.ex @7000 rpm it was a bit lean, like 0.61 bsfc. Gave it 4% more fuel 7-7250 rpm, and it went rich, and 4 hp from top was lost. 2 percent down again, and a perfect bsfc, and the power was back.
So dyno is a must if you plan at these pipes. But hey, It`s all worth it at the end
Noticed the plug color was light, and the ex temps are high at wot. But it holds together. I would never dared to run it whit these temps and plug colors if I didn`t know what the BSFC was
My plans for the summer is, BDX intake (just to get the opportunity of alot of venting in the hood), maybe a little port job, maybe lower the compression a bit, and buy a quiet silencer for the pipes.
Go for it, If you could aford a dyno tune. If not, you waste your money.
