Cat back exhaust systems

[kyle4256]

which system is good for breathing mods but not to loud and looks not bad in the bac k bumper?im just looking into a new system for mine

[minimanspk]

dont know anything about different makes of cat backs and other exhaust info but im making my own back box out of a standard back box by removing the stuff that reduces sound in the back box and welding a tip onto the end why I would say to just buy a abp centre section and weld a tip onto your standard back box
