I used to have the RK Sport header years ago, it would rub on the subframe. I heard that when RKSport made it they used an 03 cavalier, and that in 03+ the subframe was slightly moved. Does anyone here have a header on their 02 ecotec cavalier with an automatic? I would love to get a header but dont want to deal with it rubbing on the subframe. ( I did have some of the subframe grinded away to help but it still rubbed)
