Audi and SEAT Alloy Boost Hard Pipe
This alloy non-resonated boost hard pipe replaces the turbo resonated turbo outlet pipe (runs from the turbo down the left hand side of the engine) on the 1.8T 225 hp engines, as found in the Audi TT S3 225 hp (8N), SEAT Leon Cupra R (uses original mounting brackets)
The removal of the noise reasonator allows unobstructed flow on the discharge, or boost side of the turbo. We have also modified the “dent” in the underside of the pipe that allows it to clear the cam cover and made it as shallow as possible, to just allow the pipe to fit, but not overdone as to impede airflow. These combined modifications give quicker spool up of the turbo and effectively reduces the load placed upon it.
Please note that due to the production process the pipe may have minor surface marks.
