    hey guys i have the magnaflow #15782 aftercat system for sale. i took it off the truck to install the sts turbo. it was on the truck for about 5000 miles. it has dual 3" inlets and single 4" outlet with the magnaflow tip exiting in the stock place. sounds badass when you get on it but a nice deep sound cruising. the cost was over $500 but i will take $300 for local pick up only...unless you want it shipped at your expense

    you'd have to do some cutting and welding. 5.3's are single in/single out
