Mgnaflow Catback for NBS with 3inch intermediate pipe. 1 in 2 out polished muffler with 3 inch inlet, 2.5 inch outlets. Had on my truck for a year. Still in good condition. $150 located in Oklahoma City, OK. I bought it from Summit Racing last year and it originally came with pipes out the back, but I no longer have those because I tossed them when I lowered the truck. Thanks!
