they sacrifice some performance but the ease of fitment is worth something. My starter had to be pulled to install the headers but maybe if I jacked the engine up I wouldn't have had to do that. The TTI's are bead in regards to the starter.
I have never done it that way but I've seen many people talk about how it's the only way to do it, might have to try that next time. I'm assuming the torsion bars will need removed first, then unbolt the k-member.
