BLOX Racing's FR-S/BRZ Front Pipes are now available in two versions: mandrel-bent T304 and handmade GR1 Titanium. Both extremely high quality products have been designed to directly replace the factory's restrictive piping. The BLOX Front Pipe greatly reduces back pressure. With increased exhaust flow, horsepower and torque are increased. Gains are significantly increased when combined with BLOX Racing's UEL header and True-Dual exhaust system.
