See my last posting..
short tips give better gain at high RPM (better for racing)
Longer tips give better gain at lower RPM's (better for street)
Since I don't 'race ' I wanted to optimize my car for street driving, so I got
the longest ram pipes that would still allow enough clearance im my filter
housing, if I could have fit longer ones, I would have.
Basically keep in mind that you really need to evaluate how you will really be
using your car, and then make your mods according to your application. A full
race motor with every conceivable mode would be almost completely undrivable in
normal traffic, and would be a real waste of money. This is all covered in
Vizard's book.
