I like the way this guy thinks. A civic doesn't have to have the most expensive parts, and not the cheapest either, it's a cheap tuner to begin with. Most exhausts can be replicated sound wise for a fraction of the price, as you'll just be buying a brand name, reliability and/or warranty. On a dseries engine, exhausts are basically nothing, unless incorporated with forced induction. Stock mufflers especially from newer vehicles can be had for cheap (under $150). Mix things up, what's modifying a car without making modifications.?
