    Does anybody know if the stock Y pipe will clear the front driveshaft with 5" of lift on an 89. Not sure what years used the same exhaust. I will also be dropping the t case 1 to 1 1/2". Not a big deal if it does not clear but I would like to put the front shaft in to test everything out after I am done.

    i am almost sure it will if its stock. my 89 has the stock exhaust at the y-pipe, and after installing a 4" lift, i had an exhaust shop add a 1" extension on the right side, and they cut half way across the left side to allow the pipe to go down, then welded the cut. 30 bucks later, i was cruising down the road. oh yeah, my d-shaft was in the back of the truck, and i had them install it while they were at it.

    After putting a 4 inch lift on my 88 the front drive shaft was dropping onto the exhaust. Ran it in to the muffler shop and they rerouted it real nice above the drive shaft. Much better and cheap.

    I have 4" lift and dropped the t-cas with the factory spacers. My front DS has about 1" (maybe .75) clearance above the cross pipe. At full suspension drop, it may actually be rubbing, although I have no marks on the DS or the exhaust.

    I plan to have mine re-routed shortly, I would recommend the same. Do it right and do it once.

    Or, if possible in your area, do like me, buy a set of headers and get the dual kit and be done with it forever.

    I plan to get it rerouted but want to put the shaft in to test everything first. Yes I can put headers on but I don't want more stuff hanging underneith to hang up on rocks. Also I just put a new Catco converter and Flowmaster Force 2 cat back system on it a few months ago. Thanks.
