BAR-TEK® Catless Downpipes suitable for BMW S63B44 F9X M5/M8

Plug'n'Play downpipes without pre-cat suitable for the BMW M series with S63B44 Engine such as in the M5 and M8.

Real plug'n'play downpipes for easy replacement - Neat performance plus and a whole lot more sound. Due to the 76 mm Downpipe completely without catalytic converter, the back pressure is significantly reduced and the turbo is relieved. This brings more power and less exhaust gas temperature.

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

Features:

• Size pipe routing
• upper and lower Downpipe
• made of 304 stainless steel
• TIG welded
• fits on original AGA and many accessories systems

Vorkat lambda probes and sensors must be switched off by software (e.g. with MHD). The downpipes are not street legal.

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