Header and presilencer to be sold as set. Mufflers as a pair. Right muffler has slight dent that does not affect flow. I've been using the factory y-pipe. All pieces bolt right in. $175 for each or $325 all four pieces. Buyer pays shipping and boxing cost. Paypal works for me. PM me if interested in local pickup in Alabama area. Will consider driving up to 150 miles to help delivery for gas expense.
