You definitely want to avoid any direct contact between copper and 
aluminum.  Otherwise, coating connections with with any of a variety of 
materials, including the anti-corrosion compound sold for battery 
terminals, will improve useful life in bad environments.

Tinned copper braid does a good job of bonding metal parts, but if not 
protected from the weather and corrosive materials (such as road salt in 
cold climate regions), it deteriorates pretty quickly.  If you need to 
bond to the exhaust pipe to reduce rfi from the ignition system, stainless 
steel hose clamps work well to secure brass or tinned copper straps to the 
pipe, but be sure to sand the pipe first to remove surface oxidation and 
other contaminatants.

Best luck with your project.

Has anyone experienced dissimilar-metals troubles
when using copper or other grounding straps and/
or connectors in a vehicle?
