Noisy as hell. Cylinder bushings way too stiff.
Compared to Whiteline and Cobb kits this is WAY loud. The circular bushings are rock hard, which from other companies is probably 30% softer. To some this is a reasonable trade off for a tiny bit more stiffness in lateral movement. In my experience there is a SIGNIFICANT whine coming through the shaft. Compared to whiteline where it was barely noticeable, this is a constant whine almost like the trans is low on fluid. After switching over to another bushing the sound went away immediately and was certainly related to the bushing. I have a full sound system with dynamat lining the entire car and invidia exhaust and can still hear the whine clear as day. I would only rec this to people who do not care about noise.
