Just wondering if any one has installed a MBRP sido on an 07 screw sb yet. It says to cut the extension pipe to 31 inches for a screw short bed or 37 inches for a super cab. This doesn't make sense to me. I understand a six inch difference in bed lenth, but shouldn't the cab size be longer with the screw? I guess I will just cut it long first and see how it lines up, then adjust accordingly. Anyway, my first impressions of the kit is that it is very high quality with polished pipes and nice double walled tips.
