get the diff, I'm telling you won't regret it! I have a 3.38 diff in and its amazing, instant torque anytime you need it, although you'll be at a higher rpms on the freeway.

i drive on the freeway all the time, cruising at 80mph 90% of the time.....

would it be hard on the engine running such high rpms for a long period of time?

Not harder on the engine-steady highway speeds easier
on the engine than stop-and-go and I doubt if anyone
could predict/quantify accelerated wear. Your exhaust
note would likely be slightly higher/louder depending
on the muffler you run. With stock exhaust decomission
vacuum butterfly and tone should be deeper-disconnect
it anyway with or w/o diff change!

Hey guys, well I emailed Samir at Rennsport and he said he cant get the LSD diff for a while he is out of stock and who knows how long that will take. And for the 3.15 diff well its not that much different from stock, you can get a 3.46 oem for 700 dollars. As for the Header it will make your car louder and you will free up maybe 8-9hp, the problem here is what will you do with the O2 sensors since they are plugged on to the cat which is on the header. if anyone figuers this out I will be buying a header next. my .02 cents

look at it this way

a higher rear end gear for off the line quickness and
headers i say for power at higher rpm band.

Torque multiplication from a diff is constant at all vehicle speeds... The increase in performance will occur from 0 - speed limiter kicks in, at all engine RPM's. Headers are a last mod in my opinion, I think your heads/cams will be more limiting than the headers. I have a 3.46 diff sitting in the garage right now. Just waiting to put it in....
