Even with the 992 GT3’s elite motorsports pedigree, regulations and external pressures forced compromises to be made. Primary tubing length, runner diameter, and merge collection efficiency are limited even in the most purpose-built of applications, and these compromises come at the cost of sound and power. That’s where we come in.
For immediate results, addressing the restrictive factory headers is the place to start, where the assembly houses catalytic converters and particulate filters—naturally stymying the flow of exhaust through the system. Our upgraded headers are built around large-diameter, free-flowing catalytic converters with optimized cast flanges and runners for maximum gains in power, throttle response, and tone from the 992 GT3’s 4.0-liter flat-six. The resulting sound change is an amplification of the system mounted rearward, a proper emphasis on the flat-six’s sound as intended, and built to withstand aggressive driving in the most demanding environments. Our billet CNC head flanges allow for not only a more efficient transition from exhaust ports into the runners but add extra strength in a high stress area preventing the chances for any cracking from repeated, hard use during track days.
FACTORY INTEGRATION
