I recently upgrade my exhaust to replace the TRD dual exhasut muffler with a smaller Magnaflow muffler so that I would get more of a growl to go with my intake system. I cut out the piping right before the first resonator and then cut off right after the dual output of the muffler. SO you will have a resonator with piping along with the TRD muffler and thats it! i am willing to sell cheap as it now just sits on my garage taking up space. This will only work with 04-06 DC tundras. Ask my if you want a pic or 2 and ill send it to you. I live in socal by Palm Springs area!! let me know if anyone is interested!!
