I have a Flowmaster 50 series for sale. Used for a bit under a year. It's a great muffler and I love the sound but I am looking for something louder. Specs are 2.25" offset inlet, 2.25" center outlet. Paid around $100 for this new, willing to let it go for $60, or willing to trade for a complete set of the Toyota all weather rubber mats. It is in perfect condition. Local only, located in Scottsdale AZ.
