will my new jba headers perform a well?
i was running obx longtubes through pypes mid muffler set up untill last summer when i sold everything. it made 317hp and 336 tq. i just bought jba longtubes with there o/r h-pipe and im hoping it will perform atleast as well as the obx's did. any thoughts? also hows the fitment compared to the obx's? i used to have a bad problem with the header hitting the steering shaft when making right turns
