This Bull-X downpipe, or DPF replacement pipe, is designed for the Audi A6 4F with 2.7tdi and 3.0tdi engines.<\/p>\n<p>Do you want to achieve more power from your TDI while also reducing the load on the turbocharger? Then a Bull-X product is a good place to start. The downpipe has a major influence on response and performance, as it forms the link between the turbocharger and the exhaust system. The larger the pipe diameter and the greater the flow capacity, the more easily the turbocharger can discharge the processed exhaust gases through the exhaust system. This has a positive effect on torque, power and the exhaust note, particularly when combined with a modified exhaust system.<\/p>\n<h3>Benefits<\/h3>\n<ul>\n<li>The turbocharger can discharge exhaust gases more easily, resulting in increased power.<\/li>\n<li>More torque, as the turbocharger reaches operating speed more quickly and is not slowed down as much.<\/li>\n<li>Lower exhaust gas temperatures, reducing the load on the exhaust manifold and turbocharger.<\/li>\n<li>Installation is \u00bbplug and play\u00ab thanks to the OEM-style connection.<\/li>\n<li>Suitable for all Quattro and front-wheel-drive models, including facelift models.<\/li>\n<li>Manufactured from stainless steel.<\/li>\n<\/ul>\n<p>After installation, the engine management must be remapped. This product does not have sensor ports.<\/p>\n<p><strong>Note:<\/strong> Some 2.7tdi\/3.0tdi models from model years 2004\/2005 were supplied from the factory without a DPF and instead featured 2 oxidation catalytic converters. The DPF replacement pipe does not fit these models. The Bull-X downpipe, or catalytic converter replacement pipe, fits all models.<\/p>\n<p>To reduce exhaust gas temperatures even further when making larger power increases, and to make full use of the additional exhaust note in combination with a modified exhaust system, we recommend fitting the complete downpipe.<\/p>\n<p><strong>Road use:<\/strong> This product is not permitted for use on public roads and is intended solely for motorsport. Of the catalytic converters and catalytic converter replacement pipes offered, only the HJS catalytic converter with EG approval is permitted for public-road use; all other versions are intended for motorsport only.<\/p>\n<p><strong>Suitable for:<\/strong> Audi A6 III (C6).<\/p>\n<h3>Manufacturer\u2019s vehicle data<\/h3>\n<ul>\n<li>Bull-X Downpipe Unterteil\/ DPF-Ersatzrohr Audi A6 C6\/4F 2.7-3.0TDI<\/li>\n<\/ul>\n<p><em>Original product name by HG Motorsport (\u00bbz.B.\u00ab = e.g.).
