I've just finished installing the exhaust valve controller & it works perfectly, when its fully closed it sounds stock & when its fully opened there is no loss of performance, best thing i've put on my car.
Someone said they only make them for a 2 1/2 inch exhaust, not true they make em for any size.
I got it through Neugen, he was a pleasure to deal with, it took approx 10 days to recieve it & he was $50 to $60 cheaper than Greenline or anyone else.
