Invidia 3in Stainless Downpipe MY02-07

UNPARALLELED PERFORMANCE

Invidia exhaust systems are engineered with exceptional craftsmanship, premium materials, and cutting-edge design.  Their 3in downpipe with high flow catalytic converter improves engine performance significantly by reducing back pressure.  A divorced cast bellmouth enhances the flow out of the wastegate to prevent boost creep before providing a smooth transition into the 3 inch tubing for minimal restriction.  The divorced design separates the wastegate flow at turbo outlet to prevent a disruption of the main exhaust flow.  Fabrication from 304 series stainless steel ensures the downpipe lives a long rust-free life while cast stainless flanges provide a leak-proof installation.

This is a fundamental upgrade whatever your performance goals may be.  ECU re-calibration is required when fitting this part.

An additional oxygen sensor bung is provided for use with a wide band AFR gauge.  A plug is supplied if it is unused.
