wheres the cheapet place to get exhaust (named brand) looking for 2 1/2 inch and to spend around 300

Try Trubendz, they make cheap SS exhausts with good mufflers. I got my system for 260 with a Magnaflow muffler, the borla was 275 i believe. The only thing is that im not sure if they have a system specifically for the Mazda 3 yet.
