Hey guys just wanted to show you my new seyup . I thought long and hard about the exhaust setup I wanted to do on this car, should I replace the muffler? Delete res and replace muffler? Replace both? Decided to leave everything from the axle forward intact and create a straight axle back. Here's what I came up with. If Mazda ever gives me hell for warranty I just bolt up the oem one. No cutting done. I don't have a YouTube account or anything but maybe I'll start one now so I can show you guys what it sounds like.
