Here at Straightline, we are known for delivering top-notch quality performance products with zero compromises.

With great excitement, we are proud to introduce our Porsche 991.1 GT3 and GT3RS Twin Turbo Kit — designed to transform your already stout GT3 or GT3RS into a wild, turbocharged machine.

Each kit is hand-built in-house at our South Florida facility, using only the highest-quality components on the market to ensure maximum performance, efficiency, and reliability.

We begin with our hand-built turbo manifolds constructed from 321 stainless steel, engineered to efficiently channel exhaust gases into a pair of Garrett G30-660 ball-bearing turbochargers for rapid spool and exceptional power delivery.

Once the exhaust gases are expelled, they exit through our 3” stainless steel exhaust system, finished with our signature GT slash-cut tips.

Fresh air is drawn through high-flow K&N filters before passing through a Garrett liquid-to-air intercooler, delivering cool, dense air directly to the engine for optimal combustion and power output.

When the throttle plate closes, excess boost pressure is released through a Turbosmart Gen V Blow-Off Valve (BOV), while dual Turbosmart 45mm Gen V wastegates precisely regulate boost pressure.

All components are fully integrated and optimized with a custom ECU flash tune and PDK transmission tune, ensuring smooth drivability, controlled power delivery, and maximum performance.
