HKS Legamax Sports Catback Exhaust - 2022+ WRX

Symmetrically arranging the 4 silencers and the beautiful 98mm titanium tail creates a muffler that is not only powerful in the rear view but also visually appealing when the vehicle is lifted up. This exhaust system produces a pleasant bass sound at normal revs and a sporty sound when the accelerator is depressed. By changing the pipe diameter from 74.7mm to 60.5mm x 2 to 45mm x 4, the straight structure achieves low exhaust pressure while reducing unpleasant exhaust note, thus improving both performance and sound quality.

Development began with the concept of an exhaust system that prioritizes three key aspects: performance, sound quality, and appearance. By incorporating a longer pipe length, a departure from the conventional design, we successfully minimized muffled sounds and accentuated a sporty high-frequency tone around 500 Hz. Additionally, utilizing four 45 mm pipes enhances the cross-sectional area, thereby improving both performance and sound quality. Attention to detail was paramount in the design of the rear view. A symmetrical four-pipe cannon configuration, strategically positioned hook and bracket protrusions, and an intermediate pipe layout engineered to maximize floor space utilization were implemented. This meticulous design ensures minimal ground clearance while delivering a striking quad-tip appearance.

TIG welding is extensively employed in crafting the main silencer, ensuring precision and durability. Furthermore, the titanium tail produces a stunning gradation effect. These intricate designs are meticulously executed by skilled craftsmen, all done by hand, ensuring each product meets the highest standards of quality aesthetics.
