{"product_id":"s550-na-street-fighter-package","title":"S550 NA Street Fighter Package","description":"\u003cp\u003eThe S550 Mustang GT (18-23) is a great car from the factory, but like every Coyote before it, there’s a lot left on the table.\u003c\/p\u003e\n\u003cp\u003eThe Street Fighter Package is built around the upgrades that make the biggest difference without overcomplicating the car. A JLT Cold Air Intake helps the engine breathe easier, high flow catted headers open up the exhaust, and our custom tuning ties everything together so each part works the way it should.\u003c\/p\u003e\n\u003cp\u003eUsing the included Shoemaker Performance RTD4 device, we’ll build both a 93 octane and E85 calibration specifically for your car. Every tune is written around your setup, not pulled from a generic file, so throttle response is sharper, the power comes on harder, and the car feels noticeably stronger throughout the RPM range while maintaining the drivability you’d expect from a daily driven Mustang.\u003c\/p\u003e\n\u003cp\u003eThis isn’t about chasing dyno numbers. It’s about making the car feel the way it should have from the factory. Whether you’re carving up back roads, making passes at the drag strip, or just enjoying the drive home, the Street Fighter Package delivers a Mustang that’s quicker, more responsive, and simply more fun to drive.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003ePackage Includes\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eJLT Cold Air Intake\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eHigh Flow Catted Headers\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eShoemaker Performance RTD4 Tuning Device\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eCustom 93 Octane Calibration\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003eCustom E85 Calibration\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shoemaker Performance","offers":[{"title":"Factory Catback","offer_id":53426239111462,"sku":"SM24HCAT, CAI-FMG-18","price":2949.99,"currency_code":"USD","in_stock":true},{"title":"Aftermarket Catback","offer_id":53426239144230,"sku":"SM24H3CATLG, CAI-FMG-18","price":2949.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/1686\/7878\/files\/WhatsAppImage2026-07-01at4.35.08PM_1.jpg?v=1782939728","url":"https:\/\/shoemakerperformance.com\/products\/s550-na-street-fighter-package","provider":"Shoemaker Performance","version":"1.0","type":"link"}
