Pair of Flowmaster #842580 mufflers

I bought a car and it has Flowmaster 842580 mufflers on it. They are like new. They are SS and come black from flowmaster. It has 2 1/2 tubes.From what I've heard they will fit some Corvettes,Some Mustangs. They are also used to run your exhaust out the side of your car in front of the rear tire (as mine are)They are a 80 series muffler.The case is 9-1/2 in long,4 in thick,9-1/2 in wide. Both intake and exhaust are on one end of the muffler.I plan on putting some quieter mufflers on it.$100.00 plus shipping.Summit sells them for $132,00 each. I'm also selling a Aeromotive 11203 Fuel pump.It also is in perfect shape.It will support up to 750 hp and will work with alcohol .I wish to sell it for $100.00 plus shipping. Summit sells it for $221.00. I plan to go with a inside the fuel cell pump.These parts work fine but are more for a racing car rather than a street car.I have some pictures of the car that these parts are coming off in my album .Roger
