Decided its time to get an Aluminum Driveshaft for my 2013 GT Auto....Was thinking of getting one from Axel Exchange however my research shows me that it replaces the factory pinion flange ....im wondering if this is a good thing or is it better to get a driveshaft that bolts to the factory flange?....either way im looking for a hassle free vibration free easy install....my car is lowered on eibach prokit springs and currently has ZERO driveline vibration...I don't wanna go to a one piece and have a vibration....I had a bad experience with my 11 and a certain company's early model 1 piece that replaced the pinon flange but had not yet offered it with a cv joint.... im really wanting to make the correct choice the first time this time around....my car is an auto and from what I hear the autos are a lot more prone to driveline vibrations when switching to a 1 piece driveshaft...please help me make the choice!
