Yes now . With the right hand drive conversion the electric power steering was moved and the exhaust manifold had to be altered On the right hand side , and boy what a mess , they chopped it , and it doesn’t flow well at all . Same with the 2015 GT and on and the engine power has dropped at the rear wheels Because of this . The best I have seen at the drag strip for a 2018 GT 10 speed here is 12.4 @ 115 mph but still 1.9 / 2.0 in the 60 foot totally stock. . Never herd of any making 400 rwhp on a dyno either . Fitting headers makes all the difference but that’s expensive. I think a good set and hi flow cats fitted is around $3,000 plus another $1,000 for the tune .
