Ive been looking at the 3-1 headers for our trucks, anybody have them, do they trip any engine codes??? what styles of aftermarket exhaust are available?? if you keep the stock trd exhaust can you make the headers efficent or is upgrading ness. also with air intake, header, exhaust setup what kind of numbers in hp gain can you expect? do they make a performance chip for the X-R. an finally with the headers an stock exhaust does the sound tone up quite a bit? does borla make a more aggressive exhuast for a beefier tone with the headers an does anybody have any videos with sound.... finally the trd exhaust is actually borla isn't it or did i make that up??? like i said questions questions questions.......
