I have the MAC long tubes.
But from my experience, you should replace the motor mounts while your at it.
Also get the foil looking heat sleeve for the clutch cable.(not sure what it's called)
My buddy had a clearance problem w/ the steering shaft and his BBK's....I didn't
He had to get the skinny one.
Performance is OUTSTANDING...you will not regret it.
You may need to elongate the o2 sensor wires.
Other than that install is a breeze( once the headers are on)
Not sure how much you drive your car, but i reccommend deleting the smog while your at it.
It gives you soooo much more room to bolt the headers in on the pass. side.
Plus no screwing around w/ the pipe going to the h-pipe.....good luck
