Fouled Rear Bar

[Zombie]

Hey all,

I find my car gets a dirty rear bar from the exhaust quite easy and quickly (having a white car doesnt help i guess).

I think it has actually stained the paint in some parts as I have been a little lax in washing it.

Any ways of stopping it doing it without a retune?

Does the shape/angle/length of the exhaust tip effect it? I have often wondered about the actual physics behind exhaust gases going backwards on to the car.
