The APR DPK0014 Cast Inlet Downpipes replace the kinked and restrictive 60mm factory downpipes with a larger, 76mm stainless steel mandrel-bent system, featuring a port-matched cast inlet, high-flow catalyst and various other features. Expect better throttle response, significant power gains, and an intoxicating exhaust note, while remaining civilized during normal daily driving.

The APR downpipes feature investment cast, T304L downturns designed to maximize flow and minimize turbulence. The mounting flange and O2 bungs are integrated into the castings and with a wall thickness of 2.5mm, the APR downpipes produce a refined exhaust note compared to thin wall tubing systems. The cast downturn mates to a T304L flex section that is fully sealed with a corrugated inner lining to improve flow and reliability. The T304L exhaust pipe is rolled to 76mm diameter with a 1.5mm wall thickness.

APRs engineers specified high-quality, high-flow GESi metal 300-cell catalysts ideal for forced induction applications. Internally each 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 brazed 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.
