TTI head pipes

If the motor mounts are good, and the motor is in the correct location, you won't need to modify TTI's parts. You'd be surprised how far "off" an engine can be installed. All the bolt holes are either slotted or oversize. Combine that with a stack-up of tolerances, and that motor can be sitting "anywhere".
This is true. It still led to both of my dusters needing to have a ding by the driver side torsion bar. Neither were touching, but both just had a sliver of daylight. The engine will lift on that side. One has Schumacher mounts, the other has new mounts from O'reilly's.
