Hey guys...doing my own exhaust swap with the car jacked up in my driveway. PITA but....no choice. Anyway, I've got a D&D tubular K-member set up which is "supposed" to give more room to work down there...and I also noticed there were no motor mounts...just two flat metal brackets bolted to the K-member. Can I throw some poly-urethane mounts up under there to get a little more clearance? Also...I've got major steering column rubbing issued with the SALEEN shorties on there now....will the same problem occur with the bigger FATTER longtubes? Last...heard of problems with the O2 sensor wires and longtubes....supposed to be an alternate routing of the wires to get them to reach...anyone? Thanks in advance for the help.
