New exhaust

My car, a steed of steel, did once purr

Like a contented kitten, but no more.
I replaced its exhaust, and now it roars
Like a great lion, ready to devour.

The neighbors do complain, but I do not care.
I love the sound of my car's engine roar,
And I know that it is faster now, too.

So let them complain, I say. I will not care.
My car is now a beast, and I am its master.
