Yearly pics after washing

[drill3r]

Here's my car. I think the newest things are headlights and taillights update, carbon fiber exhaust tip covers, and 15mm spacers front and rear.

But guess what. I went for a drive and when I got home the exhaust tips had fallen off. haha!!! they were "secured" with thermal insulation wrapped around the stainless exhaust tips and I pushed them on.

what's a good way to secure those securely? they are plain carbon fiber covers with no holes. should i drill through them and the existing exhaust and secure a bolt and washer?

thanks!
