GTHAUS Downpipes for Infiniti Q50 Sedan 3.0 V6 Turbo / RS400 2014+

GTHAUS Downpipes for Infiniti Q50 Sedan 3.0 V6 Turbo / RS400 2014+

A dedicated MUSA downpipe set for the Infiniti Q50 Sedan 3.0 V6 Turbo / RS400 2014+, mandrel-bent to the car's own routing rather than adapted from another chassis.

The character sharpens where the engine is actually working, without the resonance that makes a loud system tiring. Freeing the rear section reduces pumping losses and usually shows up as crisper part-throttle response before it shows on a dyno.
