I don’t know what the brand was that was in my car, but it was a 3800 and was way too loose for me to enjoy driving around on the street. Based on the quality of the other speed parts on the car I would say it was probably the cheapest thing the guy could get. If I were going to go with a bigger converter again I definetly wouldn’t do more the 3200, but I also use the car as a summer daily.
