Race Ready Larini Header Race Pipe! This race pipe is the perfect complement to the Larini Sports Header. It contains 2 bungs for the stock O2 sensors. Made from stainless and perfect for the track & race car. This pipe is a high temperature resistant, hollow pipe, which replaces the highly restrictive OE catalytic converter. Exhaust flow is completely unobstructed through this 'straight-through' component. Temperatures are reduced too, as accelerated gas-flow minimizes engine-bay temperatures by dissipating heat more effectively.
