I think the up angle of your stock tips is too much. The originals had just a slight up angle not as extreme as what I see in your picture. I have never see originals that angle up that sharply. Does not look right.
I run TTI tail pipes and some custom tips from Stainless Exhaust Extensions. I had them make them with no hanger on the tip cause the TTI pipes already had the hanger and I had to get them made shorter because of the way TTI bent their tail pipes and I did not want them sticking out past stock. Mine don't angle up like originals but doesn't bother me.
The valance is original, not modified.
