For vehicles not already equipped with an APR downpipe that are upgrading to APR Stage 3, the MPK00001 Midpipe is an effective solution for the connection between the exhaust downturn and catback section.
The APR Midpipe features premium grade T304L stainless steel for its excellent appearance, strength and corrosion resistance properties. The pipe is rolled to 76mm diameter with a 1.5mm wall thickness.
APRs engineers specified a high-quality and high-flow GESi metal 300-cell catalyst ideal for forced induction application. During dyno testing, the 100mm x 100mm design showed no measurable loss in power, thanks to the catalysts specifications. Internally the catalytic converter features a proprietary blend of precious metals and loading technology that helps to reduce emissions and smell common on cat-less setups. With performance in mind, the catalyst is placed far away from the turbo outlet to reduce turbulence in the downpipe and to help reduce under-hood temperature. The low-profile catalyst features a fully captured substrate brick, which is furnace braised to the outer mantle and physically captured by the diffuser cones preventing rattling, rotation, and damage to the substrate. Subsequently, a byproduct of running the catalyst is a reduction in noise, making the system as a whole more pleasing to the ear.
