Awesome news. I found a huge exhaust leak on the manifold flang where it bolts to the CAT. the 2 flanges them selves were not seated at all on one side. Like they got 1 of the 3 bolts tight. i went and bought a badass 2 ton low profile jack and bad *** jack stands and got the car in the air almost 2 feet. makes it so nice.

THE TRANNY ISNT ****!!!!!!....the rear end is haha. which im happy with because it way cheaper and more accessible. Ring and pinion are toast but the Diff. looks fine.

im going to pull the axles next wednesday and makes sure thats all it is.

AS FOR the exhaust leak. i went ahead and welded the obvious pin holes, and obviously one of the 3 studs had to break on the flange. so once i get 3 new studs for it and some copper rtv it should be good as new. For those that cant remember, the Upstream O2 sits around 1 inch above that flange, maybe less, and this exhaust leak was huge, im pretty confident this will fix the issue.

Thanks for everyones help. ill post back when i figure out if it solved it or not. i should know pretty soon.

As for the rear end. Any suggestions? Obviously a fab 9 would be great, and i would be all over it if i hadnt bought the nitrous kit....story of my life.

Any other cheaper alternatives?
