Hey All, I'm planning on replacing my timing belt in the next couple of days and I'm wondering if anyone can tell me if the '86 325 came with the one or two piece crankshaft hub? Also, is it possible to remove the fuel injector rail without taking off the intake manifold? If so, how difficult is it to reinstall? I'd like to clean the injectors and install new o-rings but I don't want to start pulling a lot of extra parts off to do it. Lastly, can anyone recommend a decent quality cat-back exhaust system? I would like a slightly aggressive tone but not much louder than stock. Any help or suggestions would be greatly appreciated.
