Sound Test: GR Cup Intake Mod; resonator delete, Grimmspeed high flow filter and silicone post-MAF inlet pipe.
3D printed the GR Cup style intake inc 3D printed delete plug for airbox. Removed both resonators, (the intake and the airbox). High flow grimmspeed dry filter and the, silicone post-MAF inlet.
Very distinctive powerful intake whoosh like a cold air sound. Mechanical sounding agreesive suction/intake when you open the throttle. Very aggro in sport mode and when downshifting with a rev match.
As expected a hard mechanical resonation returned and grows from 3250-4500rpm ish then fades quickly to engine noise. I find it quite enjoyable personally but my exhaust is also very aggressive.
