Optimal power, performance and sound

The core values of our E46 exhaust systems, now in their Gen 3 iteration. This extensive research and development has led us to further perfect the near perfect, with your 325i or 330i as the beneficiary. A free-flow design and beefy 76mm dual exhaust tips allow 35% to 40% more airflow than in the stock system.

Substantial HP and Torque Gains

The increased flow minimizes backpressure, resulting in substantial HP and torque gains. The system’s 100% hi-polish stainless steel construction also makes a bold visual statement, while increasing durability and life expectancy. The exhaust produces a sporty mellow tone with no highway drone. Factory fit specifications are followed closely, with some weight savings. -Double-walled 76mm stainless steel tips w/ embossed logos -Polished 100% 304 stainless steel -Deep, sporty exhaust note -Large 50 mm inlet mandrel bent pipes with a straight- through design -Illustrated instruction manual -Two year warranty -Factory-comparable installation.
