well i've got a few questions. First of all i have an HPI Nitro Rush with a o.s. 18 cv-r after market shocks and proline tires with associated wheels. My first question is what kind of tunes pipe would be best for the os 18? Who makes aftermarket aluminum/graphite parts? and is the hpi rush obsolete now because of the firestorm even with the 18 in it?

Thanks in advance,
Mike
