Does This Fit Your Car?

The Wagner Tuning N55 downpipes feature larger piping and catalytic converter that are freer-flowing than the original cats for better flow and less back pressure. By removing exhaust restrictions the turbos can spool up faster which makes more boost sooner. With additional tuning, more power is available. There are downpipes that delete the primary cats and can leave the exhaust with a dirty and awful smell. These Wagner downpipes are built with a sport cat to keep the exhaust cleaner.Special software, or stand-alone engine management, will be required to keep emissions fault codes and check engine lights from appearing.
