I'm not sure about the wheel size. The manual says they're 35mm wheels. Not sure how easy they'll be to find. I'd keep an eye on Ebay. It also looks like Tower has a few still available.

As for a pipe, there are a lot of options. But before that, you're better of ditching the header. That cast header is so restrictive that any pipe will suck. I have an old-school Traxxas T-Maxx header on my FE and it helps. Of course, the fact that I ported the sleeve also helped....

i using the HPI Aluminum Heat Sink Head Purple i don't know how good that is but what pipes do you guys recommend

The header you have on there is a good start and should allow you to get some extra torque to the ground with any good med-high torqe pipe. Drag out that old copy of RC Car Driver and look for that big double-page layout of pipes to get a good idea and size from there.
