Now includes CNC machined knife edged ribs. The first and original RSR billet g-lader outlet kit. The BBM RSR outlet has far less back pressure restriction than the Rallye Golf adapter outlet. Increases boost pressure with a quicker boost build rate. A solid torque and power increase from the very low rpm's to redline. Sharper throttle response without the damping effect of the factory silencer box. Crisper G-Lader sound, minimizes droning without additional interior noise. A direct replacement for the leak-prone plastic silencer box outlet. Complete kit bolts onto any G60 G-Lader without modifications. CNC machined billet from 6061-T6 aluminum for a perfect fit. Optional port-matched G-Lader outlet housing, please see RS/RSR outlet outlet porting option link below.
