I dont see why dual would effect the performance at all if anything it should help but not always does usually the stock exhaust is fairly restrictive so open er up
Duals would be of limited benefit since you can't run two equal lengths. You can get a dual outlet muffler. The large factory cat also quiets the exhaust a lot. You can get free flowing aftermarket units that are much louder and will probably open up the performance a little. Unfortunately we are sold out at the moment (really good moving item).
Maybe a set of headers would be a good choice. Getting rid of the restrictive stock manifolds would do good. Also watch out for a loss of torque if you reduce the back pressure too much.
If you do full-length duals, do an X pipe somewhere, otherwise it MIGHT hurt low-end torque.
Way back when, we had a few people posting in the V10 forum that said they had lost low-end torque, either from headers or dual-exhaust, or other exhaust mods.
However, in the past 2-3 years, we've had plenty of people do exhaust mods and report NOT losing any low-end power. Me included.
Check out the v10 sub-forum. Several threads over there.
In summary:
The stock exhaust is pretty darned good. Minimal benefits, if any, to be had from changing just exhaust parts.
A V10 is a V10, and will never sound like a V8, nor nearly as good. Most of us think a loud V10 sounds like a pissed off loud V6. A unique sound, but not necessarily a good sound.
BTW, V10s do not sound good with dual IMHO. They sound more like Nascar than like a truck. A single exhaust helps give a smoother tone, and if done right, and be very deep too. A V10 is hard to make it sound good, my advise is aside from going with a smaller cat, there is little to be done to make it louder or better sounding.
