BAR-TEK® Catless Downpipes with OPF for 2.9L TFSI EA839 Audi RS4 & RS5 B9

Plug'n'Play downpipes without pre-cat suitable for the Audi 2.9L TFSI engines with OPF like in the RS4 and RS5 B9.

Genuine plug'n'play downpipes for easy replacement - a decent increase in power and a whole lot more sound. Due to the Downpipe completely without catalytic converter, the back pressure is significantly reduced and the turbo is relieved. This brings more power and lower exhaust gas temperature.

By retaining the original flanges and connections, the downpipes fit perfectly and without modifications to the turbos.

Features:

• Size pipe guide
• made of 304 stainless steel
• TIG welded
• fits original AGA and many accessory systems
• incl. mounting material and gaskets

Vorkat lambda probes and sensors must be switched off by software. The downpipes are not street legal.

The installation of performance increasing components requires careful handling and expert knowledge. The engine and the entire drive must be in a performance-compliant condition.
