{"product_id":"n20-catless-downpipe-w-flexible-pipe","title":"N20 Catless Downpipe w\/ Flexible Pipe","description":"The Evolution Racewerks Racing Catless Downpipe is engineered to enhance performance for N20 engines. Crafted from 304 grade stainless steel with mandrel-bent piping, it directly replaces the stock catalytic converter to allow for unimpeded exhaust flow. This design aims to improve torque, horsepower, and throttle response by allowing the turbo to spin more freely, reducing strain, and potentially increasing turbo longevity. The downpipe also offers a weight savings over the stock component.\n\nConstructed with stainless steel brackets and TIG-welded O2 sensor bungs in the factory location, this downpipe is designed for a direct fit, reusing the original V-Band flange and incorporating a flexible pipe section for easier installation. It is compatible with factory or aftermarket exhaust systems beyond the downpipe.\n\nAvailable in three finishes—mirror polished, brushed silver, or black thermal ceramic—the black ceramic coating serves the dual purpose of reducing underhood temperatures and maintaining higher exhaust gas velocity for improved turbo spool and throttle response. The manufacturer strongly recommends race software, such as Epic Motorsports Race Software, to complement this catless downpipe. This software is advised to eliminate fault codes and check engine lights associated with the downpipe's installation on stock software, pass post-race tech inspection, optimize power gains, and improve drivability.\n\nSpecial Application Notes: This racing downpipe is intended for track or race use only and is not compatible with the N26 SULEV engine. It is crucial to check the emissions sticker under the hood to confirm whether the vehicle is equipped with an ULEV (N20) or SULEV (N26) engine. Removal or alteration of emissions control equipment is illegal for use on public highways. This product is sold strictly for racing, competition, track, hobby, or other off-road applications and is prohibited on any vehicle subject to emissions inspection or control.
