Thanks for the replies everyone! After e-mailing info@ansaautomotive.com I received a speedy reply and am now in contact with Gwen, who said the price of the muffler is $201.53 (not including sales tax and shipping for me). Now all that's left is to wait for my next paycheck and then it'll be time to shoot her an e-mail and order it!

Also, from the sound of the e-mail, there's plenty of these things: she told me to let her know when I was ready to order.
