Sidepipes?

I like the Thorley Style definitely from the 70's
Patriot has some of the same style for 250 bucks
that im looking at for the Dart

Here's another site that has some nice ones too! Someone here on the site loved them on their challenger and said they weren't too loud on the highway either8)
