I have a Magnaflow catback for a 01 Dodge Ram 1500 4x4 Quad cab for sale. Magnaflow advertises this unit to fit 98-01 ECSB 1500 trucks. Unit is 2-3 years old. Being a Magnaflow it is made of 409 stainless and the outer shell of the muffler is 304 stainless won't rot out. Edited link didn't realize that a flash link won't work www.magnaflow.com the part number is 15727 Not the best looking unit anymore but still sounds good. I'm looking to get $180 from this unit (basically what it would cost me to get a replacement unit from Autozone) or I'd be willing to swap a unmolested in good shape 98-01 exhaust from another truck. This unit lists over $500 from Summit Racing so I'm offering this at a fraction of the cost. I'm selling because I don't use the truck much anymore due to gas prices and the length of my commute (120 miles round trip) and I have a company car so I'm selling the truck to my father in-law. He doesn't care for how loud it is and wants something stockish on it. Thanks for looking
