Stainless Steel Group N Subaru Impreza WRX/STI

Group N line

An engine's performance remains closely linked to its ability to efficiently reject burnt gases.

These Group N lines have been designed in collaboration with leading tuners. The shape and, above all, the tube diameter guarantee maximum engine performance by increasing power and torque.

These Gr.N lines are made of stainless steel for enhanced reliability. They are easy to fit, as the original diameter is retained at the fastening point.

STAINLESS STEEL provides better sound, weight and corrosion resistance. Last but not least, the line walls are smooth, for better exhaust gas evacuation and enhanced performance.

The lines are F.I.A. and C.S.A.I. approved.

Note that FIA CSAI regulations authorize a GR.N noise limit of 98 ±2 db.

Group N lines are not authorized for use on public roads. They are therefore not GUARANTEED.

ATTENTION: The line must be assembled in its entirety, as its components are not identical to the original ones.
