Has anyone deleted the forward resonator? if so did it make much difference?

There's a forward resonator?

 

[RooTBeeRthe1st]

Well, pretty sure I just sheared the output shaft on the transfer case. No more rear drive. But putting it in four-wheel drive still works perfect driving off the front tires only. Also doesn't make any noise even when turning.

... don't remove too much torque management...

Going to revert a few settings back to stock (or Whipple) in the tune so I don't kill something in the front end before I can fix the current problem with the rear.

Time to go shopping I suppose.
Wonder if anyone has a drop in Atlas 2. That would be pretty sweet.

California emissions!

I don't think it's required for CA. smog it doesn't have a 02 sensor I don't know if they would even notice it missing

Differential maybe.

Differential maybe.

I just figured the diff would have made a lot more noise, like metal getting bashed around inside the pumpkin.



Definitely the diff.

Didn't like the hard & fast 1>2 shifts.
Right rear let out a small bark, then a not very loud metal "ping", but everything still drove fine and I didn't see any fluids leaking.
Drove real nice for a mile or so and then on decell, another "ping".
Drove another mile or so and then accelerated maybe half throttle from a light, and as soon as it tried to go to second, another "ping" and then engine tried to rev straight to the Moon. Barely even made a sound when it let go.

time for a eaton detroit, if you can break one of those I give you kudus, most I ever did was wear the bearings out of one, took a couple years of beating on it, new bearings and she was back on the road.
