You could use a bigger drill bit to make a really shallow hole to like counter sink it.... that's if the pvc is thick enouh.. then just use some sylicone over it..
And if you can I would make it easy to romove so you can change the tuning if you want with different length pvc pieces untill you find the one that's perfect for you and your car
