The APR Cast Inlet Race DP Exhaust System replaces the restrictive factory DP 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, more horsepower and an intoxicating exhaust note, while remaining civilized during normal daily driving. It’s one of the best performance upgrade for 1.8T and 2.0T engines following APR’s ECU Upgrades and it’s designed and assembled in-house, using premium materials and world-class manufacturing techniques few can match.
Race DP with Cast Inlet: The APR Race DP features an investment-cast inlet, with a port matched v-band flange, creating an ideal flow path for exhaust gasses exiting the turbocharger. By matching the already oversized turbo outlet, the Race DP is able to maintain exhaust gas velocity, improving performance with minimal variances in cross-sectional area due to the strategic use of cast parts. Furthermore, the cast inlet allows for excellent packaging, satisfying other design criteria while maintaining a larger and constant cross-sectional area compared to mandrel bent tubing built to similar specifications. The end results it simple: Smooth exhaust flow and maximum performance!
The Race DP’s piping is upgraded to attractively-brushed, straight-through and mandrel-bent 76mm tubing, dwarfing the small 65mm factory system. Furthermore, components visible from the engine bay are tumbled for a more attractive finish. A CNC laser cut bracket provides a strong and accurately positioned mounting point to take the weight of the Race DP off the turbocharger, and the internally-corrugated flex section gives the Race DP the flex it needs under engine movement. Finally, the Race DP uses T304 stainless steel components that are TIG welded together with argon back-purging, ensuring the system not only looks great on the inside and out, but stands the test of time.
Flex Section: The APR midpipe use an OEM-style flex section that is fully sealed with a corrugated inner lining to improve flow and reliability. The low profile design and minimal use of bradding material eliminates clearance issues common with other designs that can billow, rub, rattle and fray over time. The flex section is constructed from T304 stainless steel and is argon back-purged when TIG welded to the Race DP.
Catalysts: APR’s 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 catalyst’s design.
Internally the catalytic converter feature a proprietary wash coat that helps to reduce emissions and smell common on cat-less setups. 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.
Brackets: Attached to the Race DP is a high quality mounting bracket. The bracket is constructed from T304 stainless steel and is CNC-machined and CNC-bent to exact tolerances. The bracket is TIG welded to the piping and argon back-purged.
Designed to stand the test of time, the adjustable bracket is CNC machined from 8mm-thick billet T304 stainless steel and the hanger feet are threaded into place, eliminating the need for welds. Weight is removed from the bracket, wherever possible, while not hindering its structural integrity. The bracket attaches to the Race DP’s integrated mounting bracket with the included hardware.
The factory downpipe system consists of smaller, 63mm piping with varying bends and multiple restrictive high-cell-count catalysts, all of which contribute to a less than ideal flow path and hindered performance. APR’s engineers took a multi-step approach to maximizing flow, reducing under hood temperature, and eliminating unnecessary restrictions all in a unique package.
*APR’s cast downpipe exhaust system mates perfectly to the factory catback exhaust system with the included reducer. For compatibility with most 76mm catback exhaust systems, a 76mm link pipe must be installed between the downpipe and catback. APR’s universal fit kit includes a 200mm link pipe and clamp that can be cut to length for compatibility across a wide range of systems. Click Here to view APR's Universal Fit Kit.
