I went with the traxxas blue aluminum tuned pipe, Its all top end but if you tune the rusty right you can stand it up even with the top end pipe on it and then ride that wheelie (my batt. box is so messed up) untill one wheel comes off the ground.

For all the rusty owners out there i would HIGHLY recomend getting the 0 degree axel cariers ($3-$5), They say the toe in on the stock -1 degree carriers make it less likely to slide which is such a load, the truck has enoufgh power to slide no matter what and the -1 carriers only help in brigging one wheel off the ground so you lose traction. The 0 degree will make it go straight and not wave from side to side on the straights as well
