If you have the coin get some long tubes, if not JBA shorties are still awesome and you wont be chasing codes.
Now if are looking for a true dual set up you will have to go to a custom shop and have them build it the way you want it. I don't think that any company makes a header-back true dual, bolt on product.
Now that I've started to day dream and type IF I had the money I would install American Racing long tube headers, into an X-pipe, into 2 E-cutouts, into 2 14" Si/So Magnaflow mufflers and finish it off with some 5" black tips... but that's just me. So now that you know you need to go custom start researching your possibilities, X-pipes, H-pipes, Headers and Muff's. Just be sure to let us know what your final product is and have fun!
