looking for suggestion as far as what to get for pipes etc, I want some more top end- and what pipes fit- basically I want more topend for the lake - i like the way it handles

Get the setup from www.hotseatperformance.com they got twin and single pipes, heads, clutch kits and anything and everything give them a try.

Make sure you get pipes for a prox and not an edge x as the prox has higher front shock mounts and a reinforcment bar eunning inbetween the mounts. I run the stock pipe but I softened up the spring rate front mid and back to let it squat more if it bottoms out crank up the shock settings,this will also help it to corrner flatter and you will pick up some speed to.

Pipes will help, but the sled comes from the factory geared lower for the holeshot and not the top end. *Change the gearing ratio from the stock setting.
Good Luck!
