Greddy Exhaust Drone

Exhaust wise, Z1 headers, Motordyne ART pipes, and the Greddy catback

Couple more sound clips and a quick showing of the welds and the quality of part in case anyone was curious

I had purchased the new Remark axle back exhaust last year which is made by Greddy and uses similar rear canisters/mufflers and tailpipes. Even with my stock cats and Nismo midpipe, it was absolutely unbearable. The drone was so bad that the inside of the car was shaking itself apart and after an hour drive, I had a headache that lasted the rest of the day. I removed them the same night. So yes, Greddy exhausts have a huge amount of drone that will probably only get worse as the exhaust breaks in.

I drove a G37 and a 2010 Z with the GReddy and let me tell you coming from a muffler delete in comparison the remarks are quieter. I got them for my 2018 and along the ISR resonated test pipes its quieter now than the GReddy Z. I also did the whole trunk inside with the Noico and a Hushmat. the outside i shoved the foam used in sound cabins. Drone is actually less eversince I added the foam between the bumper and the trunks space. Try it.

I have the same catback as yours. I believe the drone comes from a combination of the engine noise and the exhaust system together. Perhaps this system is more race oriented than say an Nvidia or HKS. As others said, you could insulate the cabin and the trunk to reduce the vibration feel. I personally don't care too much as the only time I'm in those rpms is when I either accelerate or have to climb a hill. I accept the extra noise because "street race car".

I love my Greddy exhaust - running with FI Resonated Test Pipes - but yea drone is very real - I ended up soundproofing my trunk and it dropped it by 10db easily. Major improvement
