Our 2.75″ Intercooler pipe kit was brought to public when during testing of larger diameter pipes for the EVO X and Ralliart. Only 1/4″ in diameter larger, but what a difference it made in looks and performance. We found that the larger diameter piping was giving us increased throttle response in our test vehicles. It also fills out the engine bay for that ‘custom’, more proportioned look.
IC Pipes are also sold seperately
