With its turbocharged 1.6-liter three-cylinder engine, impressive 300 horsepower, and a precise six-speed manual transmission, this car puts the driver in complete control. The GR-Four all-wheel-drive system provides exceptional grip and handling, especially on twisty roads or rough terrain. Combined with a lightweight body and aggressive tuning, the G.R.

The larger pipe allows for increased airflow, reducing back pressure and improving overall engine performance. Whether hitting the track or enjoying a spirited drive, you'll feel the difference in power and throttle response, with sharper acceleration and enhanced performance. Plus, the system is lighter, weighing 30.5 pounds versus the OEM's 32.5 pounds, contributing to better handling and fuel efficiency.\u003c\/p\u003e\n\u003ch2\u003eSleek, Aggressive Look\u003c\/h2\u003e\n\u003cp\u003eThe triple-tip exhaust design delivers a striking and aggressive look for your Toyota GR Corolla.

Available in three stunning finishes—Polished, Black Chrome, and Burnt Gradient—each tip is protected by a PVD (Physical Vapor Deposition) coating. This coating enhances durability and heat resistance while providing a long-lasting, premium appearance.

Ceramic fiber is lighter, more durable, and doesn't degrade as quickly as fiberglass, making it the perfect choice for long-lasting performance.

Installation is simple, thanks to a direct bolt-on fit, making this the ideal aftermarket exhaust upgrade for your G.R. Corolla. Each exhaust system is hand TIG welded by skilled craftsmen, ensuring high-quality welds for strength and precision.

For Innovative mounts with forward and back positions, the header optimizes performance in the most forward configuration. See the fitment section below for exact fitments. \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eHEADER DESIGN AND PULSE TIMING\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe equal-length 4-2-1 layout mirrors Honda's original engine design, pairing cylinders 1-4 and 2-3 to match the 1-3-4-2 firing order. This configuration maintains consistent 360-degree spacing across the 720-degree cycle, allowing the low-pressure wave from one cylinder to reach the next during overlap. The result is enhanced scavenging, reduced exhaust reversion, and a more consistent torque curve.\u003c\/p\u003e\n\u003cp\u003eAt the head, we precisely opened the flange ports to match the PRC Type R oval profile. The 304 stainless steel head flange starts as a 1\/2-inch plate and is CNC-machined down to 3\/8 inches in low-stress areas to reduce weight while maintaining flatness and rigidity. Strategically reinforced zones remain at 1\/2 inch to prevent warping and ensure a tight seal.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eRUNNERS, WELDS, AND COLLECTOR GEOMETRY\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eEach primary runner is precision mandrel-bent from 304 stainless steel, featuring a 1.5-millimeter wall thickness. The runners are flared to match the PRC oval port shape and seated approximately one-quarter inch into the CNC-machined flange.

Routing is planned so everything fits without subframe hammering or complicated mid pipes, and the header lands where it should while preserving ground clearance for lowered cars. A 2.5-inch stainless flex bellow between the header and collector absorbs engine movement and protects the welds, and allows you to easily weld it up to your exhaust of choice with the included two-bolt flange that comes in the box. \u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eLastly, many swap headers install a single O2 bung in a position that places the end of the O2 sensor where it can rub against the floorpan. We include two oxygen sensor bungs and position them to clear the chassis and protect wiring. This allows you to run both the OEM primary and secondary sensors, or you can plug the second port and use it for quick wideband access at the dyno. The goal is simple: remove installation issues for a clean and easy install. \u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eBOTTOM LINE\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eIf you're looking for a K swap header that combines performance, compatibility, and ease of installation, this is it.
