Evolution Powersports' 304 Stainless, TIG-welded X3 Race Bypass Pipe can free up additional HP and substantially lower temperatures radiating from the exhaust components. Any restriction after the turbo directly affects horsepower. The EVP Race Bypass Pipe fits just like stock and reuses the factory mounting locations and heat shields.
Additionally, EVP Race Bypass Pipes do not 'neck down' like the factory cat pipe. Rather than reuse the factory graphite doughnut, we convert the end to a ball/socket, which perfectly mates up to the OEM or any EVP X3 slip-on exhaust. This change alone made a substantial difference in back pressure when running tunes or a big turbo setup.
