{"title":"2002-2005 WRX Cat-Back Exhausts","description":"\u003cp\u003eA cat-back exhaust replaces everything from the catalytic converter rearward on your 2002-2005 WRX — mid-pipe, resonator (if equipped), and mufflers. It is the single most popular first performance modification for a reason: meaningful sound transformation, a small but real power gain once tuned, and zero emissions or inspection concerns since all factory catalytic converters stay in place.\u003c\/p\u003e\n\u003cp\u003eStart with tubing diameter. For a stock-turbo WRX, 3-inch systems are the standard and support everything up to moderate turbo upgrades. Larger diameters only help once you are making serious power; on a stock car they cost low-end response and add drone for no benefit. Material matters for longevity: T304 stainless steel is the baseline you should expect at this price point, while titanium saves 20-plus pounds but at a steep premium.\u003c\/p\u003e\n\u003cp\u003eSound level deserves honest thought about how you actually drive. \"Mild\" systems stay near stock at cruise with a deeper tone under load — the right pick for a daily driver. \"Aggressive\" systems are genuinely loud and will drone on the highway; great for weekends, tiring every day.
