Sorry for these possibly stupid questions, but I couldn't find any threads on the matter.

When I test fitted the exhaust shield last night, I had to apply pressure to the top part of the shield in order for it to sit flush with the car. First of all, is this normal?

Based on that observation, I decided to place most of the tape very close to the edges of the shield. I figured if I didn't it would result in the sheild protruding out at the top. Is this the correct way to attach it? If I look from the top or the sides I can clearly see the 3M foam tap.

Thanks
