I Have (2) Flowmaster Super 50 mufflers- 2 1/2" Offset in/ Center out. PN-52556 I bought them last year and had them on the car for about 50 miles and didnt care for the sound ( a little too quiet for me) and I cant return them now . Id like to get $200 for both ( shipped free) or pick up, I paid $150 each for them, now they are $166 each new
