if your running 3.9 gears even with 31's it will feel slow, very rough guide 33"s are best on 4.3 diffs and 35"s on 4.6 thats to keep the gearing at around std levels,

the exhaust is the same tb42, tb42e, tb45e, td42 only catch is you may have to add the bung for the o2 sensor but thats about a 10 min job
Yeah I know ratios on diffs etc lol I thought he ment geaebox as get it worked with a shift kit etc thanks
