Best fitting exhaust for blob wagon?
 

Looking to swap my Prodrive backbox for something a little louder but got a few concerns.

I really like how the Prodrive backbox fits the bumper recess and doesn't poke out far. I've since seen quite a few aftermarket exhaust sticking out way past the bumper/hanging low and looking very odd.

So can anyone share thoughts, photos etc as to what I should look at?
