The Gen-II kits include the module, vehicle specific harness, pair of exhaust block off plates, stainless mounting hardware, Free Priority Mail Shipping and as always, our excellent customer service and Limited Lifetime Warranty! The Gen-II kits don’t stop the system from running like our current V3 and V5 units, they emulate it. The secondary air injection system monitor will even show as complete/ready even with the entire system removed from the vehicle. You can remove the air pump(s), pluming, air injection control drivers and by adding Pressure Sensors Options (PSO) you can also remove the air switching valves. (PSO are also needed if you have damaged pressure sensors) Call us for details and to place your order before they are available for sale to the public on our website!
Gen-II kits are $450 and PSO options are $145 each.

Like all of our bypass kits these are sold for off-road or competition use only!
