The SXTH Element Engineering High Flow Cat Downpipe for the N Series is a complete bolt-on, turn key solution for more power out of the stock turbocharger.

The OEM design of the N dowpipe is a huge restriction in the exhaust system. We replace the stock unit with a turbine matched cast bellmouth and full 3 inch diameter tubing all the way to the factory cat-back system. Our unit is full 304 stainless steel construction with the finest TIG welds and components.

Tuning is not required to install this downpipe. We also take the necessary design steps to keep the check engine light from coming on. We also utilize OEM exhaust hangers and a large Euro-style flex section for an OEM quality installation.

Our N Downpipe is designed and built to withstand the most rigorous conditions. To help with heat management, the OEM heat shield can be reused and our Downpipe arrives to you with a full proprietary finish.

The Casting

Our main design point of this downpipe is our cast 304 stainless steel bellmouth. Using our 3D scanning and computer modeling, we can match the turbine geometry while maximizing flow into the tubing. This also allows us to make tight bend geometry while maintaining a nice and thick-walled part that can withstand the abuse of racing both on the track and auto-cross. This is far-superior to pie-cut welded tubing in every way! We can also easily retain the mounting points for factory heat shielding.


Flex Section & Catalytic Converter

All of our exhaust components that replace an OEM catalytic converter are built with High Flow, 200-400 Cell, Catalytic Converters. The flex sections of the exhaust are built with a wire mesh to aide in rigidity without compromising flexibility.

We start by 3D scanning the OEM downpipe (shown here in transparent blue) and design our new pipe using the latest in 3D CAD software. We can overlay our new design with OEM to make sure you have a perfect fit.

Performance Boost

Even though there are certain limiters in the N Engine Control Unit (ECU), our core was still able to achieve measurable power increase on our in-house dyno.  Gains can be seen across the RPM range.  This becomes more apparent on tuned ECUs where there is higher boost command and gains of up to 15whp can be achieved.
