Well remember your going to probably lose a bit of ground clearance with the True Duals, but a plus is they sound amazing. The cut-outs will sound great to when they are open, and you can close them up when things get to loud for you. And best thing is the cut-outs are alot cheaper than if you get a True Dual set-up.

Looks like you need some heads. I would save the money on duals.

If you went to a TD setup with a properly done X-merge then you would probably see some slight increase but not enough to warrant a change IMO. I would only do it in your case if you just wanted the sound of the duals. Like Orange said, I would just save that money towards heads.

I had a 3" cutout on my flowmaster catback and gained MAYBE 3 RWHP via dyno results. With the LT switch and true duals, I got 38 RWHP. . . you're call

Yea, long tubes do a lot though... I would stick to where you are and invest in something else..

I've actually seen some threads on here where guys mention that they actually lose hp from going from a setup like yours to true duals.. Something crazy happens with the back pressure in their cases I believe..

Anyway, you put down good numbers and even if there is a pony or two to be found there, it isn't enough to justify shelling out a ton of cash for trues IMO..
