aftermarket parts

[suprabahamut]

I have looked at alot of websites and found alot of aftermarket parts but no short shifters, not many exhaust manifolds, or cold air intakes, I have thought to use mandrel bent exhaust pipe and weld different bent and straight pipe together but can this work and is this legal and I found a good deal on universal 8 cylinder accel spark plug wire that you have to put on the boots are all wire about the same, and will any of these modification fail the safty inspection of the yearly car inspection test
