ebay has one for 500 or less, i think some members here have one, i couldnt afford a cat back, so i made my own, cherry bomb has one for the 4runner, but its the same things im using, cherrybomb has a 3inch center offset muffler, and use all 3 inch pipes, its different from my setting since they come with a tip, im not using a tip, but everything else is the same 3inch pipe from the flange of stock location , then to muffler and then to the exit.
