Any recommendations? Is there a pipe (or mod)out there that adds some low end grunt?

 

HSP has a speed kit for the 700. HPD use to have a pipe for the 700 but I don't see it on their site anymore. Big Gun and MBRP both have pipes for the 700. The best thing that you can do is get a clutch kit. As far as utilities go, most people have high reguards for the Heelclicker clutch kit. They claim to be able to do easy wheelies in low and even high.
