Hey, im looking for the the best choice for a catback exhaust system. This upcoming summer i am going to be doing the sr20det swap for my 1989 nissan 240sx and im gonna be building to compete in autocross events. I just got the car literally yesterday and it is bone stock. So i figured a good place to start would be the exhaust. Alot of people have been telling me to go with the Apexi Dual N1 but i also heard if i wanna put an anti sway bar or an upgraded one in the rear it won't work with the dual N1. Just curious on what you guys think.
